Functional Python Programming

Summary

In this chapter, we looked at alternatives to the if, elif, and else statement sequence. Ideally, using a conditional expression allows some optimization to be done. Pragmatically, Python doesn't optimize, so there's little tangible benefit to the more exotic ways to handle conditions.

We also looked at how we can use the operator module with higher order functions like max(), min(), sorted(), and reduce(). Using operators can save us from having to create a number of small lambdas.

In the next chapter, we'll look at the PyMonad library to express a functional programming concept directly in Python. We don't require monads generally because Python is an imperative programming language under the hood.
