Hi! Sort clean_list using list.sort()

I am stumped,

How do I Sort clean_list using list.sort() via the problem below:

messy_list = [5, 2, 1, 3, 4, 7, 8, 0, 9, -1]

clean_list = messy_list.sort

I have attempted other methods but cannot get to the correct one in order to solve this problem. Please help if you know how! Thank you!! :D

Hi Missy,

I don't see the code for task 1.

You are supposed to do the sorting on clean_list and not messy_list but first you have to create a copy of messy_list using slice syntax and store that in clean_list

Task 1 instructions - "Copy messy_list using slice syntax into a new variable clean_list."

Are you able to figure out how to slice an entire list?

It looks like there was a quiz question that had you get a slice of an entire list.

You can review the syntax in the Teacher's Notes section of this video http://teamtreehouse.com/library/python-collections/slices/introduction-to-slices

You're getting close.

You're missing the slice syntax for your first task.

The notation that you showed for clean_list[:] is what you want to do on messy_list instead.

clean_list = messy_list[:]

This creates a copy of messy_list and stores it in clean_list using slice syntax.

then in the 2nd task you want to sort clean_list not messy_list.

You should call the sort() method on clean_list.

clean_list.sort()

I hope that helps clear it up for you.

Hi Jason!

Thank you for replying back !

Sorry for not being descriptive enough before.... you are only allowed to type a certain amount of characters into the question box for the 1st ? # ahhhhkilllmenow! # jj

but anyway,

Task 1 instructions - "Copy messy_list using slice syntax into a new variable clean_list."

so yes, for the 1st task you are correct, it asked for that specific answer and I listed the answer:

clean_list = messy_list

part 2 of the ? I am stumped on...

I thought it would be:

clean_list = messy_list.sort() ....

I came up with a few other answers such as: clean_list[:] etc but all of the answers I came up with are incorrect.....

.... please help me out if you can, it would be greatly appreciated!!! Thank you so much!!
