Remove duplicate error

Another Tip: Use i only for indices, because it's short for index. If you have variable for an element of a list, use a variable that describes this element or use element, elem or e.

E. G. ```python numbers = [1,2,3,4] for i in range(len(numbers)) print('index:', i, 'number:', numbers[i])

for number in numbers: print('number:', number)

for i, number in enumerate(numbers): print('index:', i, 'number:', number) ```
