"Oh no! I have another messy list. This one has some even numbers in it and I want it to only have odd numbers. Use del to delete the 8 from messy." Currently stuck on this challenge. I can't seem to use index for numbers to delete the 8.
messy = [5, 2, 8, 1, 3]
del messy(2)

Treehouse Moderator 68,441 PointsYou're very close. The syntax for a list index is square brackets[ ]
messy = [5, 2, 8, 1, 3]
del messy[2]
Using parens acts like a function call.

508 PointsI dunno why this happens a lot with these code challenges here on Treehouse, I was having an error and I spent 10 minutes figuring out why, well if you could only correct the instructions as they explicitly ask you to delete the number 8, but for the challenge to pass you need to delete the 2.

Treehouse Moderator 68,441 PointsBe careful of syntax. The line
del messy[2]
refers to the index 2 (that is, the third element in a 0-based count) and not the integer object 2 (which could be removed using del messy[1])

508 PointsYou are totally right, I get it now!

I had del messy [2]. everything looked correct, I read the comments on here and seen, I added a space. So the correct way to write it is del messy[2].
just a tip for the ones who are still lost when everything looks correct. check for spacing errors.
