# stuck on lists.py

Task 1 clears. I have been struggling with Task 2. For some reason when I make a mistake in Task 2 the system flags Task 1. Seem to be stuck in my own perpetual loop. I have attempted at least 15 alternative solutions yet no closer to completing. No longer learning.

lists.py
```the_list = ["a", 2, 3, 1, False, [1, 2, 3]]
# Your code goes below here
the_list.insert(0, the_list.pop(3))

for item in the_list:
if item != range(1,3):
del the_list[item]
```

Welcome to Treehouse!

I can fully relate to the frustration of being stuck on some of these challenges, but you are doing great and asking questions is key!

Let's take a look at this task in particular.

Use `.remove()` and/or `del` to remove the string, boolean, and list members of `the_list`.

Here is our `list` after we have completed Task 1

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

If you remember from the course videos we can remove things explicitly with `remove()` like:

```the_list.remove("some string value")
```

or we can delete specific index values with `del` using the syntax:

```del the_list[3]
```

which would remove the item at index 3.

I hope that gets you pointed in the right direction but please post back if you are still stuck or have further questions.

Happy coding,
Ken

Excellent. I think I now understand the solution for Task 2. BUT, there must be something wrong with my Task 1 answer because it claims it longer passes once I put in Task 2! Here is my code for Task 1: -to move 1 from current location in one step. First it is accepted. Add Task 2 and it is not! the_list.insert(0, the_list.pop(3))

Can you post the current code you are using? Sometimes the challenge checker is a bit, um, picky, yeah, let's go with picky.

Ken, second try: Task 1 code that passes:

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

Task 1 doesn't pass when I attempt Task 2!

Thanks, Bob

Let's look at Task 2 this way...

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

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

# Your code goes below here
```

Keep in mind that if you are referencing items in Task 2 using index numbers, the code from Task 1 will change the index values of `the_list` for use in Task 2.

Ken

I moved my Task 1 code above the "# your code below..." (not sure if it should matter but seemed to!). I understand the index shift and used: del my_list[1, 4, 5] did not pass. del my_list[1] del my_list[4] del my_list[5] did not pass with an "index out of range" now trying a combination of remove/del to determine if remove only for text, etc. is the issue.

Ken, I finally convinced the system to accept my answer. I used the_list.remove(individual values).

I had tried every permutation; del the_list[5] kept giving me an index out of range error. Thank you for the help. I appreciate validating my Task 1 answer and the clues for Task 2.
Regards, Bob

Ken, Here is the code for Task 1:

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

a second try:

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

Thanks, Bob

Bob;

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

That works. Task 2 is built upon that so don't delete that line, just `remove()` or `del` items with code after that line.
