How do I do monkeypatching in python

Question

I had to do the following introspection in python and it didnt go too well:

name = sys._getframe(1).f_code
name = "%s:%d %s()" %(os.path.split(name.co_filename)[1],name.co_firstlineno,name.co_name)
 

For an output like this :

foo.py:22 bar() blah blah
 

In our debugging output.

I want to prepend anything to stderr with this sort of information -- Is it possible to change the behaviour of print globally within python?

Answer 1

A print statement does its IO through "sys.stdout.write" so you can override sys.stdout if you want to manipulate the print stream. I hope this works fine for you.
