I met you half-way, I showed you where the source code is.  Now you 
need to come the other half and look at the code.  Maybe start by 
grepping the entire source tree for "open"?

Ouch, that mightn't be very effective! With some function names, you
could do that. Not so much "open". Still, it'd be a start...

In Python3.3.0 -- the built in open() appears in 
Python-3.3.0/Modules/_io/_iomodule.c;
There is another module defined in an object in 
Python-3.3.0/Modules/_io/fileio.c; but I don't think that the one called 
when a lone x=open(...) is done.

Cheers.

iMath:

There is no need to download the source.  You can browse the 
source code online.  For the v3.0.0 version of open():
  hg.python.org/cpython/file/bd8afb90ebf2/Modules/_io/_iomodule.c

For 2.7.3 I think what you want is the  builtin_open() function in 
  http://hg.python.org/cpython/file/70274d53c1dd/Python/bltinmodule.c
and the file object and open_the_file() function in
 http://hg.python.org/cpython/file/70274d53c1dd/Objects/fileobject.c

Hope this helps.

oops, that should have been:
  http://hg.python.org/cpython/file/bd8afb90ebf2/Modules/_io/_iomodule.c

Your welcome.

I noticed that you, like me, are using Google Groups.  You
might want to read this page about posting from Google Groups:

  http://wiki.python.org/moin/GoogleGroupsPython

It will help you avoid double posts and other Google Groups
posting problems that annoy other people here.

depends on the python version. io in 3.x
otherwise, it is a builtin
