what am i doing wrong with the code

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

lists.py
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]
    return(messy_list.pop(3) and messy_list.insert(0, 3)

1 Answer

First of all, the return keyword needs to be used within a function, you don't need to use that here.

This task is asking you to move the 1 in the list, so you need to get that 1 first. You got that part right.

messy_list.pop(3) 

This will remove the 1 and return it

You also need to put the 1 at index 0, and you can do that with

messy_list.insert(0, 1)

so, if you want to immediately take out the 1 and put it back in index 0, you can put the .pop() call within the insert call:

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