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...

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.

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.
