Display a progress bar.

Function signature[source]

st.progress(value, text=None)

Parameters

value (int or float)

0 <= value <= 100 for int

0.0 <= value <= 1.0 for float

text (str or None)

A message to display above the progress bar. The text can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links.

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, gray/grey, rainbow.

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.

Example

Here is an example of a progress bar increasing over time and disappearing when it reaches completion:

import streamlit as st
import time

progress_text = "Operation in progress. Please wait."
my_bar = st.progress(0, text=progress_text)

for percent_complete in range(100):
    time.sleep(0.01)
    my_bar.progress(percent_complete + 1, text=progress_text)
time.sleep(1)
my_bar.empty()

st.button("Rerun")
