Map in Python is a function that works as an iterator to return a result after applying a function to every item of an iterable (tuple, lists, etc.). It is used when you want to apply a single transformation function to all the iterable elements. The iterable and function are passed as arguments to the map in Python.

In short, the map() function in Python applies a specified function to each item in an iterable and returns an iterator with the transformed results. It offers a concise way to perform the same operation on every element of a sequence, such as a list, tuple, or string.
