A project I'm currently working on uses Turbogears as a framework. I'd
like to interact with it using the tg-admin shell. We also use gettext's
_() function for internationalization. Now, this function is overwritten
in interactive mode, which causes annoying exceptions. Is it possible to
disable this behavior?

[correct overzealous snip]

>>> def displayhook(result):
.... if result is not None:
.... __builtins__._last = result
.... print result
....
>>> sys.displayhook = displayhook

Better is to explicitly import the name '__builtin__'
<URL:http://www.python.org/doc/lib/module-builtin>. The name
'__builtins__' is an implementation detail not guaranteed to be
present in any particular implementation.

import __builtin__
import sys
def displayhook(result):
if result is not None:
__builtin__._last = result
print result
