Dont know how to solve this

Don't really know what I'm doing

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

# Your code goes below here
the_list.pop(4)
the_list.insert(0)

You do seem to have the right idea. But you have a few issues:

  • remember that indexes start at 0, not 1. The value you want is not at index 4.
  • the insert method takes two arguments, the offset (you have that already), and the thing to insert
  • the pop method will return the thing that it removes.

I'll bet you can get it now without an explicit spoiler.

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

Your code goes below here

value = the_list.pop(3) the_list.insert(0, value)

Got it thanks!
