NOTE: Lambda Function can take 0 or more arguments.

Generally in Python we will define a function using def keyword .
but this lambda functions doesn't contain any def keyword .
So the syntax of lambda function is,
lambda argument list:expression.
lambda can take 0 or more arguments

map(function,sequence)
