Re^2: Perl VS Python

...with the added bonus that you don't need curly-braces.

I don't see that as a bonus. It gives the "%" key something useful to do in Vi(m?). I don't really see any of your other reasons as disadvantages either (except for macros), but to each his own...

% is so freaking awesome in python, i'm suprised perl doesnt' use it the same way

$ perl -e"die q!d %d! % 3"
0 at -e line 1.

$ perl -e"die sprintf q!d %d! , 33"
d 33 at -e line 1.

So, "%" would be nice, but "freaking awesome"?? ... I dunno. Between variable interpolation and sprintf (or Interpolation if you really want to get fancy), you get nearly the same functionality in perl, and I don't think I would miss python's "%" much (if I missed it at all, which I don't, because I don't use python).

And originally, I wasn't even talking about "%" in perl. It's freaking awesome in Vim though :-)

So, does Python not have variable interpolation? That would be a deal-breaker.

No, not like perl, it relies on % and dictionaries (hash). Ex

print "Hello %(name)s! Today is %(day)s!" % ( 'name' : 1, 'day' : 2 );

In perl that might be you might write

use Text::Sprintf::Named;
my $formatter = Text::Sprintf::Named->new(
    {fmt => "Hello %(name)s! Today is %(day)s!"}
);

$formatter->format({args => {'name' => "John", 'day' => "Thursday"}});
