No idea how to test if something isn't an integer

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

# Your code goes below heremessy_list = ["a", 2, 3, 1, False, [1, 2, 3]]

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

You aren't checking to see if its an integer! :) The challenge is saying that by the time you remove the string, the boolean, and the list, you'll only be left with integers. So just remove those three items from the list and you'll be left with integers, hope I helped!
