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

.pop() and .insert()

I used .pop and .insert to remove "1" from the list and put the "1" at the front of the list using .insert, but i'm still getting errors
messy_list = ["a", 2, 3, 1, False, [1, 2, 3]]

Hi Mathew,

You're on the right track, but the instructions say to remove the [integer] 1 from index 3. You are using pop(), which takes an index as the parameter. Check your code... you're passing in index one into the method instead of index 3. The rest is good.

Nice work! :) :dizzy:

Thanks Jason, is there a way I could do all that in one statement?

Yes you can. It's just a matter of a little combination. I won't give the answer outright, but an example would be:

my_list.insert(index, my_list.pop(index))

You just pop() as the second param. Make sense?
