HackerRank Python - Map and Lambda Function


The map() function applies a function to every member of an iterable and returns the result. It takes two parameters: first, the function that is to be applied and secondly, the iterables.
Let's say you are given a list of names, and you have to print a list that contains the length of each name.



  1. cube = lambda x: x ** 3

  2. 

  3. 

  4. def fibonacci(n):

  5.     a, b, c = 0, 1, 1

  6.     for _ in range(n):

  7.         yield a

  8.         a, b = b, a + b

  9.         

  10. if __name__ == '__main__':

  11.     n = int(input())

  12.     print(list(map(cube, fibonacci(n))))
