Python Perfect Square

Question

I\'m writing a function that takes a list L as a parameter and returns a list consisting of all the elements in L that are perfect squares.

def isPerfectSquare(         


        

Answer 1

This is a good place to use lambda. Also, no need to use list() if Python 2.x or the extra parens.

import math
def perfectSquares2(L):
    return filter(lambda n: n==int(math.sqrt(n))**2, L)
