Explain this code

Question

a=6;
Roots=[x for x in range(1,a) if a%x==0];
Print(sum(roots)==a and a>0;

#Output
True

Answer 1

Roots is the list of all the divisors of a.

The code checks if a is a Perfect Number (a Perfect Number is a positive number, where the sum of all its positive divisors is equal to the number itself).

By the way, 6 is the first perfect number, and only 51 perfect numbers are known, all of them even numbers.
