Find out, if the given number is abundant

Find out, if the given number is abundant.

Note:

In number theory, 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.

Test Data:

is_abundant(12)

is_abundant(13)

Expected output:

True

False

def is_abundant(N):
    fctr_sum = sum([fctr for fctr in range(1, N) if N % fctr == 0])
    # fctr_sum = 16 for N=12
    # fctr_sum = 1  for N=13
    return fctr_sum > N

# test
print(is_abundant(12))    # True
print(is_abundant(13))    # False
