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)
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.
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.
An optional tooltip that gets displayed next to the input.
An optional callback invoked when this time_input's value changes.
An optional tuple of args to pass to the callback.
An optional dict of kwargs to pass to the callback.
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.
The current value of the time input widget.
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)
