Hi guys, I'm currently working on a program to return whether an inputted number is perfect or not. I've found that the formula for the perfect number is If 2n-1 is prime then 2(n-1)(2n-1) is perfect.
I've worked out some code, but I'm stuck.
Def listfactors(n): For 1=2 to n/2 sum(list) If 2 = int(2/20): List.append(i)
I need help working out with line 1, how it says
, how do you write it so it goes up to n so I can divide it by 2?
