Pro Free and open-source
It's released with the MIT license. Sources are available on GitHub, distributions on SourceForge.
Pro Many integrated packages
Just to name a few: NumPy, SciPy, Sympy, Matplotlib, Pandas, pyqtgraph, cython, Jupyter

Cons
Con Memory-hungry
Can use a lot of memory (several GBs), especially when dealing with large projects.
Con Can sometimes become very slow, freeze, and become unresponsive
It becomes extremely frustrating when you have to wait for the text you've typed to appear in your editor. Furthermore, during these freezes the editor does not always queue what your're typing, so you might have to wait > 15 seconds before you can continue your editing. This quickly affects the concentration of a developer, causing flow interruption and general performance degradation.
Con Feature incomplete
Some features are locked behind a paywall. Although if you are a student, you can apply for the Student Pack.
