remove() on duplicates

Question

Accepted Answer

remove() finds and deletes the first occurrence of the given value, then stops. The list has 2 at index 1 and at index 3. Only the first one (index 1) is removed, leaving the second 2 still in the list. To remove every occurrence you'd write something like 'while 2 in nums: nums.remove(2)' or use a comprehension.
