'Removing items from a list' code challenge - single step solution?

Hi, I was able to solve the first part of this challenge in two steps, but did anyone figure out how to do it in one step? Here are the instructions:

"First, start by moving the 1 from index 3 to index 0. Try to do this in a single step by using both .pop() and .insert(). It's OK if it takes you more than one step, though!"

messy_list.insert(0,messy_list.pop(3)). pop returns the popped element. insert(0,element) puts the element at index 0.
