Python Program : To check for perfect integer

A positive integer n is said to be perfect if the sum of the factors of n, other than n itself, add up to n. For instance 6 is perfect since the factors of 6 are {1,2,3,6} and 1+2+3=6. Likewise, 28 is perfect because the factors of 28 are {1,2,4,7,14,28} and 1+2+4+7+14=28.

Write a Python function perfect(n) that takes a positive integer argument and returns True if the integer is perfect, and False otherwise.

Here are some examples to show how your function should work.

>>> perfect(6)
True
>>> perfect(12)
False

def perfect(n):
  factors_of_n=[]
  sum=0
  for i in range(1,n+1):
    if n%i==0:
      factors_of_n = factors_of_n + [i]
  for j in factors_of_n[0:-1]:
    sum=sum + j
  return(sum==n)
 

Thanks

Happy Programming !
