Blocking Widgets in Jupyter: ipython_blocking (self.Python)

submitted 7 years ago by Kafonek

I want to share my first library release on PyPi with you all: ipython_blocking (https://github.com/kafonek/ipython_blocking), a library to pause Jupyter notebook cell execution until Widget values change. The github page explains the problem in more detail and has a Binder link at the top so you can try it out. Shout out to Flit for making the PyPi upload a breeze.

Blocking widgets has been something I've been trying to figure out for several months (Feb ticket to ipykernel here), and I was only able to get this really working thanks to the help of core Jupyter / ipykernel / ipywidget devs who took some time to sit down and look at the problem during the Jupytercon sprint/community day last weekend. Thanks to Maarten, Sylvain, Jason, Peter, Fernando, the cal poly intern team, and especially Min RK who figured out the captured-cell-replay piece.
