What does the built-in map() function do?

1.  It creates a path from multiple values in an iterable to a single value.
2.  It applies a function to each item in an iterable and returns the value of that function.
3.  It converts a complex value type into simpler value types.
4.  It creates a mapping between two different elements of different iterables.

Correct Answer:

•  It applies a function to each item in an iterable and returns the value of that function.

Explanation: – The synax for map() function is list(map(function,iterable). the simple area finder using map would be like this

import math
radius = [1,2,3]
area = list(map(lambda x: round(math.pi*(x**2), 2), radius))
area
>>> [3.14, 12.57, 28.27]
