st.time_input(label, value=None, key=None, help=None, on_change=None, args=None, kwargs=None, *, disabled=False, label_visibility="visible", step=0:15:00) | |
| Parameters | |
label (str) | A short label explaining to the user what this time input is for. The label can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links. This also supports:
Unsupported elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g. 1\. Not an ordered list. For accessibility reasons, you should never set an empty label (label="") but hide it with label_visibility if needed. In the future, we may disallow empty labels by raising an exception. |
value (datetime.time/datetime.datetime) | The value of this widget when it first renders. This will be cast to str internally. Defaults to the current time. |
key (str or int) | An optional string or integer to use as the unique key for the 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. |
help (str) | An optional tooltip that gets displayed next to the input. |
on_change (callable) | An optional callback invoked when this time_input's value changes. |
args (tuple) | An optional tuple of args to pass to the callback. |
kwargs (dict) | An optional dict of kwargs to pass to the callback. |
disabled (bool) | An optional boolean, which disables the time input if set to True. The default is False. This argument can only be supplied by keyword. |
label_visibility ("visible", "hidden", or "collapsed") | The visibility of the label. If "hidden", the label doesn't show but there is still empty space for it above the widget (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible". This argument can only be supplied by keyword. |
step (int or timedelta) | The stepping interval in seconds. Defaults to 900, i.e. 15 minutes. You can also pass a datetime.timedelta object. |
| Returns | |
(datetime.time) | The current value of the time input widget. |
Example
import datetime
import streamlit as st
t = st.time_input('Set an alarm for', datetime.time(8, 45))
st.write('Alarm is set for', t)
