Whats wrong with my code?
the_list = ["a", 2, 3, 1, False, [1, 2, 3]] # Your code goes below here item = the_list.pop(3) the_list.insert(0,item) the_list.remove('a') the_list.remove(False) del the_list[:]
Welcome to Treehouse!
It looks like you're on the right track, but may have misunderstood part of one of the steps? On the step you're on (2/3), they want you to remove the list within the list - [1, 2, 3].
# You can actually accomplish this on a single line by combining the methods. # the_list.insert(0, the_list.pop(3)) item = the_list.pop(3) the_list.insert(0,item) # The first two lines here are correct. the_list.remove('a') the_list.remove(False) # The del method accepts an index value. # In this case, the list [1, 2, 3] currently has an index of 3. del the_list[:] # You can also use remove on the list as well. # the_list.remove([1, 2, 3])
Everything else looks good so far, nice job! Please let me know if you have any additional questions. Happy coding! :)

del the_list[:] is going to delete everything in
the_list. Definitely not what you want to have happen.
