WHAT IS MAP IN PYTHON

The map() function in python applies the given function to the iterable and returns a list of the results. We can pass multiple iterables to the map function.

Syntax: map(function, iterable, ...)

The returned value from map() function called a map object can be passed to functions like list, set etc

Example:

def test(n):
    return len(n)

li = ['one', 'two', 'three', 'four']

print(map(test,li))

Output:

<map object at 0x000001CA4D787E50>

The map object is located at the memory location given here.

def test(n):
    return len(n)

li = ['one', 'two', 'three', 'four']

# we have converted the map object into a list
print(list(map(test, li)))

Output:

[3, 3, 5, 4]
