Hi there,

You want to pull out each item in items with no brackets (not loopy()). Remember your colon, then print the item.

Make sense?

There are two things to fix here:

  • you should be iterating over the variable called items in your for loop, not loopy(), which is the function name.
  • your print statement is indented too far. It should be a single tab or 4 spaces.

Edit: and a third thing as Steve points out is that you need a colon to begin the loop.

The for loop is indented by 6 spaces; the print statement is indented by a further 9. While not correct, that's not preventing the challenge passing. Fixing the colon and the iterable name passes the challenge. I'm not sure that's strictly correct - what's your view on the tab/spacing requirement, Stuart? I'm not a Python guy.

Interesting. I do consider myself a Python guy and turns out I was wrong - the code works fine with the inconsistent spacing (although it's bad practice for sure!). You would definitely run into trouble with more complex code, as you'd have to make sure that any related branches were 6 or 9 spaces indented, respectively. Convention according to PEP 8 style guide is to use 4 spaces (not tabs). In practice, the tab key is used, but text editors and IDEs would automatically translate the tab keystroke to 4 space characters.

I agree. The PEP guidelines are clear enough. One for the guys to look at within these challenges. I'll raise it.

The code runs correctly even on my local interpreter, so I guess the challenge is handling it correctly - I suppose it comes down to whether or not they want to force good style or not!

I'll leave it, then. The key learning has been dealt with here.
