Python Tutorial - Map and Lambda Function

In this Python Programming video tutorial you will learn about lambda and map function in detail
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
we can see the advantage of the lambda function when it is used with the some built in functions like map reduce filter.
map is the built-in function, and this function is used to apply a function to all the element of a sequence.
syntax is,
map(function,sequence)

num1, num2 = map(int, input().split()) could you please explain where are the function and sequence in the above code?

[@auoteauote2067]

if you use different lenght lists, lenght of result list will be equal to shortest one a = [2,3,4,5] b = [1,1,1] print(list(map(lambda x,y: x+y, a, b))) # output lenght is [3, 4, 5] equal lenght b

Hi, in the square function, instead of the return, if you use yield, how to see the output? Even if i convert to a list, i am not able to see o/p in Python 3.5.2

[@AmulsAcademy]

Try this: Yield returns generator object to print the value we need to use next() list1 = [1,2,3,4] def square(x): yield x*x result=map(square,list1) for i in result: print(next(i))

[@sridharmalepati3662]

Thanks a lot for your prompt response !! Yes it worked!!

[@drsmahesan203]

In Python, lambda function is actually called as lambda expression.
