In functional programming, functions don’t have any internal state that affects the output that they produce for a given input. Ideally, every function only takes a set of input arguments and produces an output. Exploring Functional Programming in Pythonįunctional programming is a programming paradigm based on breaking down a problem into a set of individual functions. With this knowledge, you’ll be able to decide which tools to use when it comes to solving reduction or folding problems in Python.įor a better understanding of Python’s reduce(), it would be helpful to have some previous knowledge of how to work with Python iterables, especially how to loop over them using a for loop.įree Download: Get a sample chapter from Python Tricks: The Book that shows you Python’s best practices with simple examples you can apply instantly to write more beautiful + Pythonic code. What alternative Python tools are available to solve these same use cases.How to solve these use cases using reduce().What the more common reduction use cases are.You’ll also cover some alternative Python tools that can be more Pythonic, readable, and efficient than reduce(). In this tutorial, you’ll cover how reduce() works and how to use it effectively. Python’s reduce() is popular among developers with a functional programming background, but Python has more to offer. reduce() is useful when you need to apply a function to an iterable and reduce it to a single cumulative value. Python’s reduce() is a function that implements a mathematical technique called folding or reduction.
