What is map in Python?

Question

Can anyone explain map in Python with an example?

Answer 1

Map function returns the map object after applying the function on all the elements of the set of specified values stored in the iterables like list, tuple, etc.

Syntax:

Map (function, list or tuple)

Example:

# Return square of n

def addition(n):

                return n*n 

# We double all numbers using map()

numbers = (1, 2, 3, 4)

result = map(addition, numbers)

print(list(result))

Output:

[1, 4, 9, 16]
