The map() in Python is a built-in function. For each item of the iterable (e.g. list, tuple, etc.), the map() calls the defined function and returns a list of results. The first argument in the map() is that you need to pass a function without calling it. This means that there are no parentheses.

The operation performed by map() is usually known as a mapping, as it maps every item in an iterable input to an iterable new item. This is achieved by applying map() to all things in the input iterable.

Python uses the map concept from functional programming. The map operation considers the mapping function and the data vector as arguments and returns the new vector, which results in the development of the mapping function on each vector object.
