Removing item from list in for loop removes from both lists

list1 = [1, 2, 3]
list2 = list1

for i, x in enumerate(list2):
    print(list1, list2)
    del list2[i]

returns

[1, 2, 3] [1, 2, 3]
[2, 3] [2, 3]
[2] [2]

when I expect it to return

[1, 2, 3] [1, 2, 3]
[1, 2, 3] [2, 3]
[1, 2, 3] [2]

I am new to python and was wondering if I am doing something wrong or missing something.

edit:

list1 = [1, 2, 3]
list2 = list1.copy()

for i in list1:
    print(list1, list2)
    list2.remove(i)

fixed it

>Solution :

If you want to solve this, you need to create a copy of x into a new item which can be done with the copy module

from copy import copy

list1 = [1, 2, 3]
list2 = copy(list1)

for i, x in enumerate(list2):
    print(list1, list2)
    del list2[i]
