For some reason, it's saying that 'the_list' doesn't have the right items in it. At the end of the code, I put 'the_list.extend(range(4, 21))'

Treehouse Guest TeacherThis actually helped me find a place where I didn't test answers well enough. I've updated the code challenge so it should be more clear when this happens.
Thanks!

Treehouse Guest TeacherSo long as the_list only has [1, 2, 3] in it by that point, what you have above should work. Can you show me what code you currently have?
Stephen Whitfield
16,771 PointsOh! Sorry. When I did "the_list.pop(1)", I should have put '3' because that was the position of the "1". I confused it with the 'remove' method. Lol! It's all clear now :)

the_list.pop(1) the_list.insert(0, 1)
the_list.remove("a") the_list.remove(False) the_list.remove([1, 2, 3])
the_list.extend(range(4, 21))

Treehouse Guest TeacherDid you run this in Workspaces or your local computer? There's a bug in how you're using .pop(). .pop() removes by index, not by value, so the_list.pop(1) gets back 2 (which is in the 1 index spot), so after your the_list.insert(0, 1), your the_list looks like [1, 'a', 3, 1, False, [1, 2, 3]].
Fix that bug and the rest of your code should work fine.

the_list.extend(range(4,21)
worked for me. I would advise to check your .pop() code and try again.
