[Python] [20] [demo experimental practice examples] [looking for "complete count"]

Original title:

If a number is exactly equal to the sum of its factors, this number is called "count them." E.g. 6 = 1 + 2 + 3. After programming to find all the numbers less than 1000.

 

My code:

# ! / Usr / bin / Python 
# encoding = UTF-8 
# - * - Coding: UTF-8 - * - 

#   a number of factors if it is exactly equal to the sum, this number is called "complete count." E.g. 6 = 1 + 2 + 3. After programming to find all the numbers less than 1000. 

X = int (INPUT ( " Please The INPUT Number: \ n- " ))   # for labeling, the number of how many complete range finding; 

for I in Range (2, X +. 1):    # digital-X. 1 
    S 0 = # factor sum 
    K = int (0.5 * I) + 1'd for J in Range (. 1 , K):
         IF (J == 0% I) and (J =! I): 
            S = S + J
             #
    print("==>",i,j,s)
    if i == s :
        print("################",i)
