lambda functions in python

 Anonymous Functions:

• In Python, an anonymous function is a function that is defined without a name. 
• While normal functions are defined using the def keyword, in Python anonymous functions are defined using the lambda keyword. 
• Hence, anonymous functions are also called as lambda functions.

Use of lambda or anonymous function:

• Lambda function is mostly used for creating small and one-time anonymous functions. That means, Lambda function can take any number of arguments and must return one value in the form of an expression
• Lambda functions are mainly used in combination with the functions like filter(), map() and reduce().

Syntax:

1. Variable=lambda [argument(s)] :expression

Example program:

1. sum = lambda val1, val2: val1 + val2

   print ('The Sum is :', sum(20,40))

   print ('The Sum is :', sum(-10,40))
