I can't add an int to a list

Question

list == []

def MultiplesNumber(a):
    for i in range(1, a+1):
             if a % i == 0:
                    return i

list.append(MultiplesNumber(100))
TypeError: descriptor 'append' requires a 'list' object but received a 'int'

I can't add i to list, any idea?

Answer 1

Two things are wrong with your code:

• You are doing a list == [] which returns a True or False since == is a comparison operator. In this case it returns False. You need to use = to initialize a variable.
• list is the name of a built-in type in python, use something else as your variable name.

Fixing both of them :

alist = []

def MultiplesNumber(a):
    for i in range(1, a+1):
             if a % i == 0:
                    return i

alist.append(MultiplesNumber(100))

gives the correct output.

Answer 2

list is the inbuilt keyword which shadows your list variable. You need to assign a list to a variable not check its equality.

lst = []


def MultiplesNumber(a):
    return [x for x in range(1, a + 1) if a % 2 == 0]


lst.append(MultiplesNumber(100))
print(lst)
