💪🏼Lambda Functions

Lambda Functions are anonymous functions. It can have any no of articles but only one expression.

All these functions can be used in python directly.But,there exist many other functions in python that requires importing in order to use it on Python.

📲How to Import Functions?

Refer the example given below that is used to find the squareroot of a number

from math import *
print(sqrt(100))
