I have found something similar, despite my previous post. But you can
normally break the and and or long clauses with backslash
line-continuators. You can also break strings similarly:
a = "This is a really long line that ordinarily would " \
"be long. Test message: %s " % ( message_string)

I wouldn't worry about it if I were you. Once they know how to program
in Python then you can work on that. Probably more important to be
taught the reasons behind PEP8. You could probably say that many coders
recommend that lines not exceed 80 characters, and state that code in
the standard library has to be less than that, but that on occasion
longer lines are probably not going to kill them.
