print to cout from embedded python

Question

I am using python's very high level layer to embed some python code to a commercial application that supports a proprietary scripting language. The problem is that the application itself is coded in C++ and it has a embedded log window which displays cout and cerr. I was wondering if there is a way to print to cout/cerr from python... I already goggled a lot about it, but I cannot find a simple way to do it.

Thanks!

print goes to stdout and stderr I need it to go to cout and cerr. — Mac

It depends on how the C++ application captures the output... If it reassigned the actual low-level file-handles then print in Python will work, otherwise you might have to make special Python functions to be called instead of print. — Some programmer dude

Any idea how this special functions would be? Print simply does not work I tried it already... — Mac

There is no simple way. The application itself must assign file-likes to sys.stdout and sys.stderr in order to capture them.

You can do it using these calls:

import sys
sys.stderr.write('blah blah\n')
sys.stdout.write('blah blah\n')

or alternatively using these ones:

print >> sys.stderr, 'blah blah'
print >> sys.stdout, 'blah blah'
