Python's map() Function: Transforming Iterables

Python’s map() is a built-in function that allows you to process and transform all the items in an iterable without using an explicit for loop, a technique commonly known as mapping. map() is useful when you need to apply a transformation function to each item in an iterable and transform them into a new iterable. map() is one of the tools that support a functional programming style in Python.

In this course, you’ll learn:

  • How Python’s map() works
  • How to transform different types of Python iterables using map()
  • How to combine map() with other functional tools to perform more complex transformations
  • What tools you can use to replace map() and make your code more Pythonic
