Does python have preprocessor directives

+1 vote

Are there Python 'preprocessor directives'?
I'd like to have something like '#ifdef' to mix code from Python 2 and 3 in a single file. Is that possible? How?

1.Python doesn't define a preprocessor, and CPYthon doesn't implement one. Nothing to stop you from doing so, however.
2.It's quite possible that you don't need a preprocessor do what you want, since Python does much less compile-time checking than C. Also, it's possible to store function objects and module objects in variables, and thus to hide many things from the body of the code.
One biggie is print, since that's a reserved word (and a statement) in Python 2.x. But if you're using 2.7 you can use from __future__ import print, or something like that, and just use 3.x function semantics.

This isnt a huge issue, but I am wondering. I am running Mac OS X, I tried to configure with --with-valgrind and this is the error that I got:

configure: error: Valgrind support requested but headers not available

Now, I have valgrind installed, so it should work, yes?If someone has any extra info on this, Id appreciate it.
