gettext and the interpreter

[Hans-Joachim Widmaier]

Recently I wanted to do some debugging using one module of my first
Python program using the gettext module. I just didn't find a way to
disable the interpreter binding the last result to _, which ought to
be (and stay) a function.

Anybody got an idea how to do it?

Try redefining sys.displayhook, e. g.:

import sys, __builtin__
def myhook(value): .... if value is not None:
.... __builtin__.__last__ = value
.... sys.stdout.write("%r\n" % value)
.... sys.displayhook = myhook
Now the last non-None value will be stored in __last__ instead of _:
1 1 _ Traceback (most recent call last):
File "<stdin>", line 1, in ?
NameError: name '_' is not defined __last__
