What am I doing wrong?

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

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

del messy_list("a")
del messy_list(False)

If you run this in a workspace you'll receive a better error message:

    del messy_list("a")                                                                               
       ^                                                                                              
SyntaxError: can't delete function call

So first instinct may be to switch to square brackets - but no:

    del messy_list["a"]                                                                               
TypeError: list indices must be integers or slices, not str

Finally use integers for list indices: 

del messy_list[1]
del messy_list[3]
del messy_list[3]
