This phrase normally parses as "Python does not consider a class
definition as a separate namespace. In contrast, Python does consider a
function definition as a separate namespace." If you meant "Python does
not consider a class definition as a separate namespace *in the same way*
that it does for function definitions," saying so would make life easier
for the fairly large number of readers of this newsgroup whose first
language isn't English.
Language abuse: it's not just Python. A donation of just $5 will keep a
programmer in prepositions for a month. $50 will supply enough articles
to keep a small company understandable for over a year. With your
generous help, we can beat this scourge!
Normal service will now be resumed.
