Beginners can simply be told they are keywords. If they then come across them in other contexts, hopefully there'll be a sensible documentation page that a web search for "<keyword> keyword" would lead to an explanation that "Some Python keywords can only ever be used with that meaning. Others can be used with other meanings where the context makes it clear that the keyword interpretation does not apply. You are recommended not to use such keywords as names in your own programs. The feature was implemented to make porting existing code to future versions of Python simpler." The tutorial should contain a similar passage.
