Answer to Question #293763 in Python for Ahmad12345

Question

An integer number is said to be a perfect number if its factors, including 1 (but not the number itself), sum to the number. For example, 6 is a perfect number, because 6 = 1 + 2 + 3. Write a method perfect that determines whether parameter number is a perfect number. Use this method in an application that determines and displays all the perfect numbers between 1 and 1000. Display the factors of each perfect number to confirm that the number is indeed perfect.

Answer 1

def isPerfect( n ):
    
    sum = 1
    
    i = 2
    while i * i <= n:
        if n % i == 0:
            sum = sum + i + n/i
        i += 1
    
     
    return (True if sum == n and n!=1 else False)
 
print("Below are all perfect numbers till 10000")
n = 2
for n in range (10000):
    if isPerfect (n):
        print(n , " is a perfect number")
