Thank you, but let me rephrase it. I'm already using str.format() but I'd like to use '%' (BINARY_MODULO) operator instead.

I've looked into the source code of CPython 2.7.5 and I've found no evidence of the thousands separator been implemented on formatint() in "Objects/unicodeobject.c".

I also didn't find the _PyString_FormatLong() used in formatlong(). Where is _PyString_FormatLong() located?

So, the question is: Where would I change the CPython 2.7.5 source code to enable '%' (BINARY_MODULO) to format using the thousands separator like str.format() does, such as:

>>>sys.stderr.write('%,d\n' % 1234567)
1,234,567

Could a separate instance like the  I/O device of a subprocess
to be easily available in Python?

The next question would be whether the flow of several I/O data streams could be easily piped and manipulated in the high level
programming designs without consuming too much resources.

I'm sorry but I don't understand your question.

Do you mean returning the output of another process to the caller? Like:

import subprocess
output = subprocess.check_output(['ping', 'google.com'])

Don't worry. I guess most people on this list don't understand it either.

It looks like dihedral is a bot although nobody knows for sure. Search 
for some other posts from him/her/it in the archive and form your own 
opinion.

IMHO you can simply ignore him/her/it.

Bye, Andreas
