:x: Problematic code:
array = [1, 2, 3, 4, 5] for i in range(len(array)): print(i, array[i])
:heavy_check_mark: Correct code:
array = [1, 2, 3, 4, 5] for i, n in enumerate(array): print(i, n)
Emitted when code that iterates with range and len is encountered. Such code can be simplified by using the enumerate builtin.
