36.Python Lambda

Python Lambda:
    Usually,we know we define a function with function name,but it is also possible to define a function without a function name.Such functions are known as anonymous functions or Lambda functions.These anonymous functions defined with a  Lambda keyword in python.That is,a lambda function is a small anonymous function.It can take any number of arguments but must have only one expression.For this reason,Lambda functions are used only when we need one expression to calculate the result.

For example,consider a simple program to multiply two numbers.
def multiplication(a,b):
    return a*b
    The above program has only one expression a*b,this can also be made simple by using Lambda/Anonymous function
lambda arguments:expression
k=lambda a,b:a*b
    Where,k is a variable to store the result of Lambda(anonymous function).a,b are the arguments/parameters.a*b is the expression.
Lambda functions are most commonly used with filter,map,reduce.
