Linked the GitHub, but here's a post about why it was worth spending a few weeks compiling this list: https://sedimental.org/awesome_python_applications.html

I like Mayavi, but I wouldn’t say it was a ‘great’ Python application; it’s a pain in the install for e.g. Something like NumPy or AstroPy are clearer successful scientific Python projects to my mind.

As somebody learning Python right now...Thank You!

This is really awesome, thank you for doing this!
