What is Lambda Function ?

Lambda Function also referred to as ‘Anonymous function’ is the same as a regular python function but can be defined without a name. While normal functions are defined using the def keyword, anonymous functions are defined using the lambda keyword.

Why Lambda Function is used ?

when we require a nameless function for a short period of time. In Python, we generally use it as an argument to a higher-order function (a function that takes in other functions as arguments). Lambda functions are used along with built-in functions like filter() , map() etc.

Python Lambda Function Syntax:

lambda arguments: expression

How to use Lambda Function:

# calculate squares using lambda
squares = lambda x: x*x
print('with lambda: ', squares(6))

Result:- with lambda:  36
