st.write

Displays arguments in the app.

This is the Swiss Army knife of Streamlit commands: it does different things depending on what you throw at it. Unlike other Streamlit commands, st.write() has some unique properties:

  • You can pass in multiple arguments, all of which will be displayed.
  • Its behavior depends on the input type(s).
Function signature[source]

st.write(*args, unsafe_allow_html=False, **kwargs)

Parameters

*args (any)

One or many objects to display in the app.

Each type of argument is handled as follows:
Type Handling
str Uses st.markdown().
dataframe-like, dict, or list Uses st.dataframe().
Exception Uses st.exception().
function, module, or class Uses st.help().
DeltaGenerator Uses st.help().
Altair chart Uses st.altair_chart().
Bokeh figure Uses st.bokeh_chart().
Graphviz graph Uses st.graphviz_chart().
Keras model Converts model and uses st.graphviz_chart().
Matplotlib figure Uses st.pyplot().
Plotly figure Uses st.plotly_chart().
PIL.Image Uses st.image().
generator or stream (like openai.Stream) Uses st.write_stream().
SymPy expression Uses st.latex().
An object with ._repr_html() Uses st.html().
Database cursor Displays DB API 2.0 cursor results in a table.
Any Displays str(arg) as inline code.

unsafe_allow_html (bool)

Whether to render HTML within *args. This only applies to strings or objects falling back on _repr_html_(). If this is False (default), any HTML tags found in body will be escaped and therefore treated as raw text. If this is True, any HTML expressions within body will be rendered.

Adding custom HTML to your app impacts safety, styling, and maintainability.

Note

If you only want to insert HTML or CSS without Markdown text, we recommend using st.html instead.

**kwargs (any)

delete

**kwargs is deprecated and will be removed in a later version. Use other, more specific Streamlit commands to pass additional keyword arguments.

Keyword arguments. Not used.

Returns

(None)

No description

Examples

Its basic use case is to draw Markdown-formatted text, whenever the input is a string:

import streamlit as st

st.write("Hello, *World!* :sunglasses:")

As mentioned earlier, st.write() also accepts other data formats, such as numbers, data frames, styled data frames, and assorted objects:

import streamlit as st
import pandas as pd

st.write(1234)
st.write(
    pd.DataFrame(
        {
            "first column": [1, 2, 3, 4],
            "second column": [10, 20, 30, 40],
        }
    )
)

Finally, you can pass in multiple arguments to do things like:

import streamlit as st

st.write("1 + 1 = ", 2)
st.write("Below is a DataFrame:", data_frame, "Above is a dataframe.")

Oh, one more thing: st.write accepts chart objects too! For example:

import streamlit as st
import pandas as pd
import numpy as np
import altair as alt

df = pd.DataFrame(np.random.randn(200, 3), columns=["a", "b", "c"])
c = (
    alt.Chart(df)
    .mark_circle()
    .encode(x="a", y="b", size="c", color="c", tooltip=["a", "b", "c"])
)

st.write(c)
