An abundant number or excessive number is a number for which the sum of its proper divisors is greater than the number itself. 
The integer 12 is the first abundant number. Its proper divisors are 1, 2, 3, 4 and 6 for a total of 16 (> 12).
Derive function `abundantNumber(num)/abundant_number(num)` which returns `true/True/.true.` if `num` is abundant, `false/False/.false.` if not.
def abundant_number(num):
    return (sum([e for e in range(1,num) if num%e==0]) > num)
def abundant_number(num):
    return (sum([e for e in range(1,num) if num%e==0]) > num)
