Map Function In Python

Map functions expects a function object and any number of iterables like list, dictionary, etc. It executes the function_object for each element in the sequence and returns a list of the elements modified by the function object

As the name suggests it maps the each object in iterable to function object, returning iterable.

Basic Syntax:

map(function_object, iterable1, iterable2,...)

For Example:

def multiply2(x):
  return x * 2
    
map(multiply2, [1, 2, 3, 4]) 

In the above example, map executes multiply2 function for each element in the list i.e. 1, 2, 3, 4 and returns [2, 4, 6, 8]

Output:

[2, 4, 6, 8]
