python function not working properly it doesn't return the values that user should be getting

Question

def divisors(n):
    ans =0
    for i in range(n):
        i += 1
        k=n%i
        if k!=1:
            ans=i
    return ans
print(20)

I have a function that's not working properly when I run it prints the n value instead of printing out the divisors.

Answer 1

Three key issues are:

1. k=n%i returns the remainder - if the remainder != 1 it doesn't mean that i is a divisor!
2. in the for-loop you keep overriding ans and at the end of the function you return the value that was found on the last iteration that satisfied the if condition. What you want to do instead is to accumulate all the anss into a list and return that list.
3. The print at the end is not calling the function - it simply prints the number 20.

I'm not posting a corrected solution because I think that it will be a good exercise for you to fix these bugs by yourself, good luck!
