How do I remove the list?

Hey guys how do I remove the last element that's also a list? thanks

lists.py 
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]

messy_list.pop(3)
messy_list.insert(0, 1)

messy_list.remove(0)
messy_list.remove(3)

Well, you are actually using the 'remove'-method kind of wrong. You should type in the value which you want to have removed, not the index. Like so : 

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

# Your code goes below here
messy_list.insert(0, messy_list.pop(3))

messy_list.remove("a")
messy_list.remove(False)
messy_list.remove([1, 2, 3])

Hope that helpes.

There's a couple of ways to do this.

You could continue to use the remove method, and just give it the list you want removed as an argument, or you could use the del keyword and reference the list item by providing its position in the outer list as an index.
