But it looks like you didn't preserve the original indentation levels, so (for example) things that used to be inside a loop are not any more.
When moving code into the function, the indentation level needs to be increased one stop for every line, whether it was originally indented or not.

231,271 PointsI guess that space issue is a checker bug, right?
Chris Freeman
Treehouse Moderator 68,454 PointsMaybe. Let's ask Kenneth Love: Is the space between "main" and "()", while syntactically forgiven by the interpreter, really an error?
I remember an early version of the checker (now fixed) rejected "main(): " if there were trailing spaces after the colon.

Treehouse Guest TeacherIt's "forbidden" by PEP 8 so I'd say it should be a point of failure. It's a bad habit and one I'd rather not allow/encourage.
If I could require a PEP 8 pass on every challenge, I would....n't always?...but would most of the time.
Chris Freeman
Treehouse Moderator 68,454 PointsAdding a PEP8 check as a separate independent check would be great! Leading to "your code passes, but whoa! clean it up! PEP8 errors:....."

whileloop inside themainfunction.
