List doesn't have correct items in it

When I preview the output, it's showing the right numbers, not really sure what I'm doing wrong

the_list = ["a", 2, 3, 1, False, [1, 2, 3]]

# Your code goes below here
the_list.insert(0, the_list.pop(3))
the_list.remove([1, 2, 3])

the_list.extend(range(2, 21))

When I preview your code, the list I get is: [1, 2, 3, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20], which includes the numbers 2 and 3 twice. Make sure your extend isn't duplicating numbers that are already in the list. Happy coding!
