# It keeps saying I cant just add another list but move it. What am i doing wrong?

What am I forgetting to do?

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

# Your code goes below here

the_list.pop(0)
the_list.insert(0,1)
```

Hi Bryce,

I don't know if it was by accident but you opened this question 12 times. Please, for future use, open a question just once, someone will help you out eventually. If it takes some time to post the question, please just wait a bit until it is up on the board. :)

Welcome to Treehouse!

I don't have a ton of experience with Python, but I think I can help you with this. Let's walk through your code...

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

the_list.pop(0) # This is removing the "a" at index 0. You want to remove the 1 at index 3.
the_list.insert(0,1) # This is inserting a new 1 at index 0.

# You can do this in one step by using the pop method inside insert.
the_list.insert(0, the_list.pop(3)); # Pop the value at index 3 and insert it at index 0.
```

Remember that the index values of a list start at 0. This will be important in the rest of the challenge.

Please let me know if anything is unclear, or if you get stuck on the other challenge steps. Happy coding! :)

Hi Bryce,

The challenge is asking you to move the "1". It is at index 3, not 0.

```the_list.pop(3)
the_list.insert(0, 1)
```

passes for me.
