Functional Programming in Python Book free chapter

A comprehensive introduction to functional in Python. This book covers:

• The three Python paradigms - functional, object-oriented, and procedural programming.
• Functions as objects, using functions as arguments and return values, lambda functions.
• Mutable and immutable objects, the advantages of immutability, singletons.
• Recursion, including tail recursion and memoization.
• Closures and inner functions.
• Iterators, iterables, sequences and lazy iteration.
• Transforming iterables with map, filter, and zip
• Reducing iterables and the map-reduce pattern.
• Comprehensions and generator comprehensions.
• Generators.
• Partial application and currying with built-in functions and the oslash library.
• Functors and monads with the PyMonad library.

No prior knowledge of functional programming is required, just a working knowledge of Python.
