Introduction: This is a widget which allows users to implement small python functions dynamically and interactively. It uses the codemirror library to create the input area. The goal of this widget is to let students implement functions that can be given by tutors as assignments. The function becomes an actual python function that can be immediately run (and that it is run in a sandboxed environment, without access to the jupyter notebook global variables). It is also possible to select a custom code theme. This widget is particularly useful in combination with AppMode and/or voila.

Try it with Binder !

Installation

You can install using pip:

pip install widget_code_input

Or if you use jupyterlab:

pip install widget_code_input
jupyter lab build

If you are using Jupyter Notebook 5.2 or earlier, you may also need to enable the nbextension:

jupyter nbextension enable --py [--sys-prefix|--user|--system] widget_code_input

There are seven different code themes can be chosen. They are “eclipse”, “idea”, “material”, “midnight”, “monokai”, “nord” and “solarized”. You can check the appearance of the code themes at:
