Using `list.sort()` and attempting to access an element of the list will result in an error. ```py -a_list = [3, 1, 2] -a_new_list = a_list.sort() # This will be None +inplace_list = [3, 1, 2] +a_new_list = inplace_list.sort() # This will be None print(a_new_list[1]) # This will error because it is NoneType and not a list -a_list = [3, 1, 2] -sorted(a_list) -print(a_list[0]) # You may expect 1, but it will print 3 +outofplace_list = [3, 1, 2] +sorted(outofplace_list) +print(outofplace_list[0]) # You may expect 1, but it will print 3 ``` To avoid these errors and unexpected results, it is required to assign the result of `sorted(...)` to a new variable and use `list.sort()` method in the original list. This way, the original list will be sorted and the new list will be created with the sorted elements. |
