This is a common gotcha:

You could solve it by defining _() locally like so:


def foobar(translate):
     _ = gettext.gettext
     if not translate:
         # I try to mask the global _() builtins-function
         def _(txt):
             return txt
     return _('minutes')

However, you might not need this, because the following seems to 
work for me:

def orig_and_trans(msg):
     return (_(msg), msg)

print('The translated string "{}" is originally 
"{}".'.format(*orig_and_trans("hello")))
