How to make a copy of a list of objects not change when modifying the original list? [duplicate]

Answer 1

Use deepcopy

Return a deep copy of x.

from copy import deepcopy

original_list = [Object1(), Object2(), Object3()]
copy_list = deepcopy(original_list)
original_list.pop()

But note that slicing will work faster in your case:

copy_list = original_list[:]
