Python Python Collections (2016, retired 2019) Lists Removing items from a list

messy_list issue

I thought this would be easy. Of the indices I want to delete (0,4,5), I'd start with the highest so as not to mess up the index positions. So I removed 5, then 4, and finally 0. It worked in workspaces.

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

# Your code goes below here
del messy_list[5]
del messy_list[4]
del messy_list[0]

In task 1 of 2 you move the 1 (index 3) to index 0, and then messy_list would look like this:

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

Remember to not remove the code from task 1, because this will make the code fail.

But the instructions don't say to just remove items. In fact, task 1 says "start by moving the 1 from index 3 to index 0".

So for task 1, you will only be changing the order, nothing will be permanently removed. Then in task 2 you'll remove things from the re-ordered list.

In all multi-task challenges each task build on the previous one. Unless the instructions explicitly say otherwise, each task's code will remain as-is while you add code for the next.
