# Streamlit emoji shortcodes

Below are all the emoji shortcodes supported by Streamlit.

Shortcodes are a way to enter emojis using pure ASCII. So you can type this `:smile:` to show this
:smile:.

(Keep in mind you can also enter emojis directly as Unicode in your Python strings too — you don't
*have to* use a shortcode)
