Let's consider the following problem. A list of numbers is given: numbers = [1, 2, 3, 4, 5, 6] Our task is to leave only even numbers in the list. We may be tempted to write the following code: for i in numbers: if i % 2 != 0: del numbers[i] This solution is incorrect because we iterate over the object from which we remove elements (this causes some element skips in the iterable object and results in a wrong answer). Select the obtained numbers list.
