In this Kata we are passing a number (n) into a function. 
Your code will determine if the number passed is even (or not). 
The function needs to return either a true or false. 
Numbers may be positive or negative, integers or floats.
Floats are considered UNeven for this kata.
def is_even(n):
    a = n / 2
    if a == int(a):
        return True
    else:
        return False
def is_even(n):
    a = n / 2
    if a == int(a):
        return True
    else:
        return False
