List cleaner leaves half the items behind

Time: 0:00

What it should do

remove_evens(nums) should return the list with all even numbers removed.

What goes wrong

remove_evens([2, 4, 6, 1]) returns [4, 1] — one of the even numbers survives.

Hints

This is a mutation and copying bugs bug

Assignment does not copy, a shallow copy still shares its contents, and mutating methods return None.
