Redirecting standard out in a single namespace

[Fuzzyman]

Hello,

I'm trying to redirect standard out in a single namespace.

I can replace sys.stdout with a custom object - but that affects all
namespaces.

There will be code running simultaneously that could import sys
afterwards - so I don't want to make the change in the sys module.

I have an idea to redefine __import__ for the relevant namespace - so
that an attempt to import sys will return a different module with a
custom object for stdout. As sys is a builtin module this might not
work for the print statement, which is what I want to redirect.

I'm not in a position to test my idea until later :

__import = __import__
def __import__(name):
    if name == 'sys':
        return __import('newsys')
    else:
        return __import(name)

import sys

Is there another way to shadow the sys module from a single namespace ?

All the best,
