How do I do monkeypatching in python?
<p>I've had to do some introspection in python and it wasn't pretty:</p>

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

<p>To get something like</p>

<pre><code>foo.py:22 bar() blah blah
</code></pre>

<p>In our debugging output.</p>

<p>I'd ideally like to prepend anything to stderr with this sort of information -- 
Is it possible to change the behaviour of print globally within python?</p>

<p>A print statement does its IO through "sys.stdout.write" so you can override sys.stdout if you want to manipulate the print stream.</p>
