Generally speaking, don't append or remove values from a list in a loop like that.

There is a nice pythonic way to do it: Turn it into a set (only has 1 item of each) and then transform that set into a list.

numbers = [1, 2, 2, 2, 2, 2, 2, 2, 3, 4, 5]
numbers = list(set(numbers))
print(numbers)
>>> [1, 2, 3, 4, 5]
