How do i remove different types from a list?

cant seem to get this to work...

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

# Your code goes below here
messy_list.insert(0, messy_list.pop(3))
test_list = messy_list.copy()
for item in test_list:
    if item == list or item == str or item == bool:
        messy_list.remove(item)

Optionally, you could make the test more compact by looking for everything with a type other than what you want to keep:

    if type(item) != int:
