python grammar

[tpochep]

Hello.

In 'augop' non-terminal :

http://docs.python.org/ref/augassign.html

the delimiter '//=' was skipped. Why?

In 'Boolean operations':

http://docs.python.org/ref/Booleans.html

In 'expression' rule - what does 'if', 'else' mean? I guess 'if' and
'else' must be keywords, not non-terminals.

Probably an oversight. //= is relatively new.

Yes, those refer to literal keywords.

I'd judge both of those as errors in the web page. There is a link on the
page for reporting problems.
