Using isinstance to check for str and bool. It seems like this should work but I'm not getting past this level.
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]] messy_list.pop(3) messy_list.insert(0,1) for n in messy_list: if isinstance(n, str): messy_list.remove(n) elif isinstance(n, bool): messy_list.remove(n)

Your idea is good, but there are a couple of implementation issues:
- altering a list while iterating on it can cause items to be skipped, use a copy for the loop
- besides str and bool, there's also a list to remove
- hint: try just removing everything but what you want to keep
