That python code produces a syntax error:

File "w.py", line 3
print b
^
IndentationErro r: expected an indented block

So, not the same then!

:)

This sequence of posts is intended to stir up a debate just for
the sake of a debate. It's a time sink. It's up to you wether you
want to post to this thread or do something useful. :)

Because you're posting this to newsgroups, it would be advisable to use
only spaces for indentation -- tabs are removed by a lot of newsreaders,
which means your Python readers are going to complain about
IndentationErro rs.

Personally, I think you should not do this over comp.lang.pytho n (and
perhaps others feel the same way about comp.lang.perl. misc?) Can't you
start a Yahoo group or something for this? What you're doing is
probably not of interest to most of the comp.lang.pytho n community, and
might me more appropriate in a different venue.

Unfortunately, there are now two ways to post screwed up Python
code, and using tabs is only one of them.

The other is to post from Google Groups, and that's what Xah Lee
is doing.

(The rest of your advice, about going away, is pretty good though. ;-)

You have already proven you don't know Perl, but now it turns
out, you don't know Python either.

Go away.

Intentional fallacy -- there's no necessary correlation between what
he *intends* to do and what he actually succeeds at doing. As noted,
Xah *intends* to use his expertise in Perl to teach Python to others.
All he's succeeding in doing is demonstrating his incompetence at
both. As for myself, I suspect it's just a cunning approach to Let's
You And Him Fight.
