Resetting a list during a loop can be avoided by creating a new list within the loop and appending the necessary values to it. Alternatively, you can use list comprehension or generator expression to create a new list from the existing list without modifying the existing list. Another option is to use a copy of the original list, which can be modified within the loop without affecting the original list.

Here is an example of creating a new list within a loop:

my_list = [1, 2, 3, 4, 5]
new_list = []
for i in my_list:
    if i % 2 == 0:
        new_list.append(i)

print(new_list)  # Output: [2, 4]

Here is an example of using a copy of the original list:

my_list = [1, 2, 3, 4, 5]
copy_list = my_list.copy()
for i in copy_list:
    if i % 2 == 0:
        my_list.remove(i)

print(my_list)  # Output: [1, 3, 5]
