Pandas DataFrames as interactive HTML DataTables

In Jupyter Notebook, Jupyter Lab, Google Colab, VS Code and PyCharm

Pandas DataFrames are central to Data Analysis in Python. In this post, we introduce the itables Python package that enhances how these DataFrames are displayed, by turning them into interactive HTML DataTables.

Using itables is as simple as

What's new in Jupytext 1.3?

Jupytext's Word Cloud

The image was generated with the wordcloud package - see this notebook.

We are also looking for a logo for Jupytext. Please let us know if you can help!

Did you ever had to debug some large cell in a Jupyter notebook? In the below I share my experience on the subject. We'll review the classical methods for debugging notebooks, and finally I'll show how to set breakpoints in PyCharm for code being execute in a jupyter notebook, and benefit of the comfort of a real Python IDE for debugging.

Debug in the notebook

Before I actually describe what Pycharm can do, we quickly review the jupyter commands for debugging.

	This is a script that concatenates mp4 files using the method recommended at
	https://trac.ffmpeg.org/wiki/Concatenate, i.e. it does the equivalent of
	ffmpeg -i input1.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate1.ts
	ffmpeg -i input2.mp4 -c copy -bsf:v h264_mp4toannexb -f mpegts intermediate2.ts
	ffmpeg -i "concat:intermediate1.ts\|intermediate2.ts" -c copy -bsf:a aac_adtstoasc output.mp4

	To run this script, execute
	python mp4concat input1.mp4 input2.mp4 ... --output output.mp4
	in a Python environment in which 'click' is installed (execute 'pip install click' otherwise)

	every time you save it, if

	- and if the notebook is not `Untitled...`
