In the interpreter "_" is used to store the return value of the last
statement executed. So when this line is run:
>>> i18n_test.help
"_" is set to 'Aidez-moi!'.
A possible fix, which I have not tested in your context, would be to
explicitly set _ to _ after your module is loaded.
So, try this:
>>> import i18n_test
>>> _ = i18n_test._
... The rest of your code here
I don't know for sure that this will work. From what I have tried
though, assigning to _ seems to disable that feature of the
interpreter.
