messy_list not working

My code looks like this. Please help me understand why it is not working. Task1 is executed, but when I try Task2, it gives an error telling that Task1 is failing

messy_list = ["a", 2, 3, 1, False, [1, 2, 3]] x = messy_list.pop(3) messy_list.insert(0,x) remove messy_list('a', False, [1,2,3])

lists.py
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]
x = messy_list.pop(3)
messy_list.insert(0,x)
remove messy_list('a', False, [1,2,3])

remove is a method which takes one argument. So you have to do it like this:

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

# Your code goes below here

messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]
x = messy_list.pop(3)
messy_list.insert(0,x)
messy_list.remove("a")
messy_list.remove(False)
messy_list.remove([1, 2, 3])
