In this two-part series, I will discuss how to import ideas from the functional programming methodology into Python in order to have the best of both worlds. This first post will explore how immutable data structures can help. The second part will explore higher-level functional programming concepts in Python using the toolz library. Why functional programming? Because mutation is hard to reason about. If you are already convinced that mutation is problematic, great. If you're not convinced, you will be by the end of this post. read more
