Factors ERROR

[AdamJae]

def factors(n):
    list = []
    for x in range(2, n+1):
       while n % x == 0:
           list.append(x)
           n = n//x
       if n == 1:
           return list

I produced some code to give me a list of prime factors of any number. But when I execute the code it produces this:
factors(10075)
Out[99]: [5, 5, 13, 31]
It pastes two of the same prime factor, why is this?
Need URGENT help, please!
Thank you all <3

because that is what your code is doing
5*5*13*31 = 10075
if you don't want repeating factors - you can use set() to get just unique elements from your list
and don't use list as variable name - it's a built-in function. you don't want to override it

Oh, I am so stupid... Thank you very much!
