Just to make sure I understand, I'm going to restate your question:
Is there a way to capture stdout?
The answer: Sure, replace it with something file-like:
>>> import sys, StringIO
>>> default = sys.stdout
>>> writer = StringIO.StringIO()
>>> sys.stdout = writer
>>> print 'Whatever'
>>> sys.stdout = default
>>> print writer.getvalue()
