st.code

st.subheader

Table to concat. Optional.
Pyarrow tables are not supported by Streamlit's legacy DataFrame serialization
(i.e. with <tt class="docutils literal">config.dataFrameSerialization = &quot;legacy&quot;</tt>).
To use pyarrow tables, please enable pyarrow by changing the config setting,
<tt class="docutils literal">config.dataFrameSerialization = &quot;arrow&quot;</tt>.

data

The named dataset to concat. Optional. You can only pass in 1
dataset (including the one in the data parameter).

**kwargs

Concatenate a dataframe to the bottom of the current one.

add_rows

The Altair chart object to display.

altair_chart

If True, set the chart width to the column width. This takes
precedence over Altair's native <cite>width</cite> value.

use_container_width

The theme of the chart. Currently, we only support &quot;streamlit&quot; for the Streamlit
defined design or None to fallback to the default behavior of the library.

theme

Display a chart using the Altair library.

Data to be plotted.
Pyarrow tables are not supported by Streamlit's legacy DataFrame serialization
(i.e. with <tt class="docutils literal">config.dataFrameSerialization = &quot;legacy&quot;</tt>).
To use pyarrow tables, please enable pyarrow by changing the config setting,
<tt class="docutils literal">config.dataFrameSerialization = &quot;arrow&quot;</tt>.

Column name to use for the x-axis. If None, uses the data index for the x-axis.
This argument can only be supplied by keyword.

Column name(s) to use for the y-axis. If a sequence of strings, draws several series
on the same chart by melting your wide-format table into a long-format table behind
the scenes. If None, draws the data of all remaining columns as data series.
This argument can only be supplied by keyword.

The chart width in pixels. If 0, selects the width automatically.
This argument can only be supplied by keyword.

width

The chart height in pixels. If 0, selects the height automatically.
This argument can only be supplied by keyword.

height

If True, set the chart width to the column width. This takes
precedence over the width argument.
This argument can only be supplied by keyword.

Display an area chart.
This is just syntax-sugar around st.altair_chart. The main difference
is this command uses the data's own column and indices to figure out
the chart's spec. As a result this is easier to use for many &quot;just plot
this&quot; scenarios, while being less customizable.
If st.area_chart does not guess the data specification
correctly, try specifying your desired chart using st.altair_chart.

area_chart

io.open().
Raw audio data, filename, or a URL pointing to the file to load.
Raw data formats must include all necessary file headers to match the file
format specified via <tt class="docutils literal">format</tt>.
If <tt class="docutils literal">data</tt> is a numpy array, it must either be a 1D array of the waveform
or a 2D array of shape <tt class="docutils literal">(num_channels, num_samples)</tt> with waveforms
for all channels. See the default channel order at
<a class="reference external" href="http://msdn.microsoft.com/en-us/library/windows/hardware/dn653308(v=vs.85).aspx">http://msdn.microsoft.com/en-us/library/windows/hardware/dn653308(v=vs.85).aspx</a>

The mime type for the audio file. Defaults to 'audio/wav'.
See <a class="reference external" href="https://tools.ietf.org/html/rfc4281">https://tools.ietf.org/html/rfc4281</a> for more info.

format

The time from which this element should start playing.

start_time

The sample rate of the audio data in samples per second. Only required if
<tt class="docutils literal">data</tt> is a numpy array.

sample_rate

audio

balloons

Display a bar chart.
This is just syntax-sugar around st.altair_chart. The main difference
is this command uses the data's own column and indices to figure out
the chart's spec. As a result this is easier to use for many &quot;just plot
this&quot; scenarios, while being less customizable.
If st.bar_chart does not guess the data specification
correctly, try specifying your desired chart using st.altair_chart.

bar_chart

figure

If True, set the chart width to the column width. This takes
precedence over Bokeh's native <cite>width</cite> value.

Display an interactive Bokeh chart.
Bokeh is a charting library for Python. The arguments to this function
closely follow the ones for Bokeh's <cite>show</cite> function. You can find
more about Bokeh at <a class="reference external" href="https://bokeh.pydata.org">https://bokeh.pydata.org</a>.
To show Bokeh charts in Streamlit, call <cite>st.bokeh_chart</cite>

argument can only be supplied by keyword.

Insert containers laid out as side-by-side columns.
Inserts a number of multi-element containers laid out side-by-side and
returns a list of container objects.
To add elements to the returned containers, you can use &quot;with&quot; notation
(preferred) or just call methods directly on the returned object. See
examples below.
Columns can only be placed inside other columns up to one level of nesting.
<div class="admonition warning">
Warning
Columns cannot be placed inside other columns in the sidebar. This is only possible in the main area of the app.
</div>

columns

Insert a multi-element container.
Inserts an invisible container into your app that can be used to hold
multiple elements. This allows you to, for example, insert multiple
elements into your app out of order.
To add elements to the returned container, you can use &quot;with&quot; notation
(preferred) or just call methods directly on the returned object. See
examples below.

container

The data to edit in the data editor.
<div class="admonition note">
Note
Mixing data types within a column can make the column uneditable.
Additionally, the following data types are not yet supported for editing:
complex, list, tuple, bytes, bytearray, memoryview, dict, set, frozenset,
datetime.timedelta, decimal.Decimal, fractions.Fraction, pandas.Interval,
pandas.Period, pandas.Timedelta.
</div>

Desired width of the data editor expressed in pixels. If None, the width will
be automatically determined.

Desired height of the data editor expressed in pixels. If None, the height will
be automatically determined.

If True, set the data editor width to the width of the parent container.
This takes precedence over the width argument. Defaults to False.

Whether to hide the index column(s). If None (default), the visibility of
index columns is automatically determined based on the data.

hide_index

Specifies the display order of columns. This also affects which columns are
visible. For example, <tt class="docutils literal">column_order=(&quot;col2&quot;, &quot;col1&quot;)</tt> will display 'col2'
first, followed by 'col1', and will hide all other non-index columns. If
None (default), the order is inherited from the original data structure.

column_order

Configures how columns are displayed, e.g. their title, visibility, type, or
format, as well as editing properties such as min/max value or step.
This needs to be a dictionary where each key is a column name and the value
is one of:
<ul class="simple">
<li><tt class="docutils literal">None</tt> to hide the column.</li>
<li>A string to set the display label of the column.</li>
<li>One of the column types defined under <tt class="docutils literal">st.column_config</tt>, e.g.
<tt class="docutils literal">st.column_config.NumberColumn(&quot;Dollar values”, format=”$ %d&quot;)</tt> to show
a column as dollar amounts. See more info on the available column types
and config options <a class="reference external" href="https://docs.streamlit.io/library/api-reference/data/st.column_config">here</a>.</li>
</ul>
To configure the index column(s), use <tt class="docutils literal">_index</tt> as the column name.

column_config

Specifies if the user can add and delete rows in the data editor.
If &quot;fixed&quot;, the user cannot add or delete rows. If &quot;dynamic&quot;, the user can
add and delete rows in the data editor, but column sorting is disabled.
Defaults to &quot;fixed&quot;.

num_rows

Controls the editing of columns. If True, editing is disabled for all columns.
If an iterable of column names is provided (e.g., <tt class="docutils literal">disabled=(&quot;col1&quot;, &quot;col2&quot;))</tt>,
only the specified columns will be disabled for editing. If False (default),
all columns that support editing are editable.

An optional string to use as the unique key for this widget. If this
is omitted, a key will be generated for the widget based on its
content. Multiple widgets of the same type may not share the same
key.

An optional callback invoked when this data_editor's value changes.

Display a data editor widget.
The data editor widget allows you to edit dataframes and many other data structures in a table-like UI.
<div class="admonition warning">
Warning

</div>

data_editor

The edited data. The edited data is returned in its original data type if
it corresponds to any of the supported return types. All other data types
are returned as a <tt class="docutils literal">pd.DataFrame</tt>.

The data to display.
If 'data' is a pandas.Styler, it will be used to style its
underlying DataFrame. Streamlit supports custom cell
values and colors. It does not support some of the more exotic
pandas styling features, like bar charts, hovering, and captions.

Desired width of the dataframe expressed in pixels. If None, the width
will be automatically calculated based on the column content.

Desired height of the dataframe expressed in pixels. If None, a
default height is used.

If True, set the dataframe width to the width of the parent container.
This takes precedence over the width argument.
This argument can only be supplied by keyword.

Configures how columns are displayed, e.g. their title, visibility, type, or
format. This needs to be a dictionary where each key is a column name and
the value is one of:
<ul class="simple">
<li><tt class="docutils literal">None</tt> to hide the column.</li>
<li>A string to set the display label of the column.</li>

</ul>
To configure the index column(s), use <tt class="docutils literal">_index</tt> as the column name.

Display a dataframe as an interactive table.
This command works with dataframes from Pandas, PyArrow, Snowpark, and PySpark.
It can also display several other types that can be converted to dataframes,
e.g. numpy arrays, lists, sets and dictionaries.

The contents of the file to be downloaded. See example below for
caching techniques to avoid recomputing this data unnecessarily.

An optional string to use as the name of the file to be downloaded,
such as 'my_file.csv'. If not specified, the name will be
automatically generated.

file_name

The MIME type of the data. If None, defaults to &quot;text/plain&quot;
(if data is of type str or is a textual file) or
&quot;application/octet-stream&quot; (if data is of type bytes or is a
binary file).

mime

An optional boolean, which disables the download button if set to
True. The default is False. This argument can only be supplied by
keyword.

Display a download button widget.
This is useful when you would like to provide a way for your users
to download a file directly from your app.
Note that the data to be downloaded is stored in-memory while the
user is connected, so it's a good idea to keep file sizes under a
couple hundred megabytes to conserve memory.

download_button

Insert a single-element container.
Inserts a container into your app that can be used to hold a single element.
This allows you to, for example, remove elements at any point, or replace
several elements at once (using a child multi-element container).
To insert/replace/clear an element on the returned container, you can
use &quot;with&quot; notation or just call methods directly on the returned object.
See examples below.

empty

An optional, keyword-only argument that specifies an emoji to use as
the icon for the alert. Shortcodes are not allowed, please use a
single character instead. E.g. &quot;🚨&quot;, &quot;🔥&quot;, &quot;🤖&quot;, etc.
Defaults to None, which means no icon is displayed.

Unsupported elements are unwrapped so only their children (text contents) render.
Display unsupported elements as literal characters by
backslash-escaping them. E.g. <tt class="docutils literal">1\. Not an ordered list</tt>.

If True, initializes the expander in &quot;expanded&quot; state. Defaults to
False (collapsed).

expanded

Insert a multi-element container that can be expanded/collapsed.
Inserts a container into your app that can be used to hold multiple elements
and can be expanded or collapsed by the user. When collapsed, all that is
visible is the provided label.
To add elements to the returned container, you can use &quot;with&quot; notation
(preferred) or just call methods directly on the returned object. See
examples below.
<div class="admonition warning">
Warning
Currently, you may not put expanders inside another expander.
</div>

expander

experimental_data_editor

A short label explaining to the user what this file uploader is for.
The label can optionally contain Markdown and supports the following
elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links.
This also supports:
<ul class="simple">
<li>Emoji shortcodes, such as <tt class="docutils literal">:+1:</tt> and <tt class="docutils literal">:sunglasses:</tt>.
For a list of all supported codes,
see <a class="reference external" href="https://share.streamlit.io/streamlit/emoji-shortcodes">https://share.streamlit.io/streamlit/emoji-shortcodes</a>.</li>
<li>LaTeX expressions, by wrapping them in &quot;$&quot; or &quot;$$&quot; (the &quot;$$&quot;
must be on their own lines). Supported LaTeX functions are listed
at <a class="reference external" href="https://katex.org/docs/supported.html">https://katex.org/docs/supported.html</a>.</li>
<li>Colored text, using the syntax <tt class="docutils literal">:color[text to be colored]</tt>,
where <tt class="docutils literal">color</tt> needs to be replaced with any of the following
supported colors: blue, green, orange, red, violet.</li>
</ul>
Unsupported elements are unwrapped so only their children (text contents) render.
Display unsupported elements as literal characters by
backslash-escaping them. E.g. <tt class="docutils literal">1\. Not an ordered list</tt>.
For accessibility reasons, you should never set an empty label (label=&quot;&quot;)
but hide it with label_visibility if needed. In the future, we may disallow
empty labels by raising an exception.

Array of allowed extensions. ['png', 'jpg']
The default is None, which means all extensions are allowed.

If True, allows the user to upload multiple files at the same time,
in which case the return value will be a list of files.
Default: False

accept_multiple_files

A tooltip that gets displayed next to the file uploader.

An optional callback invoked when this file_uploader's value
changes.

An optional boolean, which disables the file uploader if set to
True. The default is False. This argument can only be supplied by
keyword.

Display a file uploader widget.
By default, uploaded files are limited to 200MB. You can configure
this using the <cite>server.maxUploadSize</cite> config option. For more info
on how to set config options, see
<a class="reference external" href="https://docs.streamlit.io/library/advanced-features/configuration#set-configuration-options">https://docs.streamlit.io/library/advanced-features/configuration#set-configuration-options</a>

file_uploader

<ul class="simple">
<li>If accept_multiple_files is False, returns either None or
an UploadedFile object.</li>
<li>If accept_multiple_files is True, returns a list with the
uploaded files as UploadedFile objects. If no files were
uploaded, returns an empty list.</li>
</ul>
The UploadedFile class is a subclass of BytesIO, and therefore
it is &quot;file-like&quot;. This means you can pass them anywhere where
a file is expected.

A string that identifies the form. Each form must have its own
key. (This key is not displayed to the user in the interface.)

If True, all widgets inside the form will be reset to their default
values after the user presses the Submit button. Defaults to False.
(Note that Custom Components are unaffected by this flag, and
will not be reset to their defaults on form submission.)

clear_on_submit

Create a form that batches elements together with a &quot;Submit&quot; button.
A form is a container that visually groups other elements and
widgets together, and contains a Submit button. When the form's
Submit button is pressed, all widget values inside the form will be
sent to Streamlit in a batch.
To add elements to a form object, you can use &quot;with&quot; notation
(preferred) or just call methods directly on the form. See
examples below.
Forms have a few constraints:
<ul class="simple">
<li>Every form must contain a <tt class="docutils literal">st.form_submit_button</tt>.</li>
<li><tt class="docutils literal">st.button</tt> and <tt class="docutils literal">st.download_button</tt> cannot be added to a form.</li>
<li>Forms can appear anywhere in your app (sidebar, columns, etc),
but they cannot be embedded inside other forms.</li>
</ul>
For more information about forms, check out our
<a class="reference external" href="https://blog.streamlit.io/introducing-submit-button-and-forms/">blog post</a>.

form

A short label explaining to the user what this button is for.
Defaults to &quot;Submit&quot;.

A tooltip that gets displayed when the button is hovered over.
Defaults to None.

Display a form submit button.
When this button is clicked, all widget values inside the form will be
sent to Streamlit in a batch.
Every form must have a form_submit_button. A form_submit_button
cannot exist outside a form.
For more information about forms, check out our
<a class="reference external" href="https://blog.streamlit.io/introducing-submit-button-and-forms/">blog post</a>.

form_submit_button

The Graphlib graph object or dot string to display

figure_or_dot

If True, set the chart width to the column width. This takes
precedence over the figure's native <cite>width</cite> value.

Display a graph using the dagre-d3 library.

graphviz_chart

The anchor name of the header that can be accessed with #anchor
in the URL. If omitted, it generates an anchor using the body.
If False, the anchor is not shown in the UI.

anchor

An optional tooltip that gets displayed next to the header.

Display text in header formatting.

header

The object whose information should be displayed. If left
unspecified, this call will display help for Streamlit itself.

Display help and other information for a given object.
Depending on the type of object that is passed in, this displays the
object's name, type, value, signature, docstring, and member variables,
methods — as well as the values/docstring of members and methods.

Monochrome image of shape (w,h) or (w,h,1)
OR a color image of shape (w,h,3)
OR an RGBA image of shape (w,h,4)
OR a URL to fetch the image from
OR a path of a local image file
OR an SVG XML string like <cite>&lt;svg xmlns=...&lt;/svg&gt;</cite>
OR a list of one of the above, to display multiple images.

image

Image caption. If displaying multiple images, caption should be a
list of captions (one for each image).

Image width. None means use the image width,
but do not exceed the width of the column.
Should be set for SVG images, as they have no default image width.

If &quot;auto&quot;, set the image's width to its natural size,
but do not exceed the width of the column.
If &quot;always&quot; or True, set the image's width to the column width.
If &quot;never&quot; or False, set the image's width to its natural size.
Note: if set, <cite>use_column_width</cite> takes precedence over the <cite>width</cite> parameter.

use_column_width

Display an image or list of images.

Function signature[source]
st.caption(body, unsafe_allow_html=False, *, help=None)
Parameters
body (str)	The text to display as Github-flavored Markdown. Syntax information can be found at: https://github.github.com/gfm. This also supports: Emoji shortcodes, such as `:+1:` and `:sunglasses:`. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes. LaTeX expressions, by wrapping them in "$" or "$$" (the "$$" must be on their own lines). Supported LaTeX functions are listed at https://katex.org/docs/supported.html. Colored text, using the syntax `:color[text to be colored]`, where `color` needs to be replaced with any of the following supported colors: blue, green, orange, red, violet.
unsafe_allow_html (bool)	By default, any HTML tags found in strings will be escaped and therefore treated as pure text. This behavior may be turned off by setting this argument to True. That said, we strongly advise against it. It is hard to write secure HTML, so by using this argument you may be compromising your users' security. For more information, see: https://github.com/streamlit/streamlit/issues/152
help (str)	An optional tooltip that gets displayed next to the caption.
