ExecBox - Execute Python code from inside your Streamlit apps!

Execbox is basically a text editor plus exec().

Installation

First install Streamlit (of course!) then pip-install this library:

pip install streamlit
pip install st-execbox

Example usage

import streamlit as st
from execbox import execbox


# Draw a text editor and a "Run" button. When you press "Run", the code in the editor executes!
execbox()


# Makes the code run automatically on each keystroke.
execbox(autorun=True)


# Draw an execbox with some initial text.
execbox("""
a = 10
b = 20
st.write(a + b)
""")

Parameters

The execbox() function accepts any of the following arguments:

• body (str. default: '')

  The initial code to show in the execbox.

• button_label (str. default: 'Run')

  The label to use for the "Run" button.

• autorun (bool. default: False)

  Whether the code should execute with each keystroke.

• height (int or None. default: None)

  The height of the execbox, in pixels. If None, calculates the height smartly to fill the content and a couple more lines.

• line_numbers (bool. default: False)

  Whether to show line numbers.

• key (str or None. default: None)

  An optional string 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.

To-do

Just one to-do:

• Write tests! Contributions accepted 😉
