I implemented the dictionary and use it in the code just fine, but the 
doctest still fails :(

My teststr.py module is:

#--[---------------------------------------------------------------
if __name__ == "__main__":
     # install gettext for testing this module because of the string 
translation
     # performed in the code.
     import gettext
     gettext.install('impathpl', './locale', unicode=False)
     presLan_en = gettext.translation('impathpl', "./locale", 
languages=['en'])
     presLan_en.install()

def onOffStr(isOn) :
     """Return the "ON" string for True, "OFF" for False.

     **Example**

     >>> onOffStr(True)
     'ON'
     >>> onOffStr(False)
     'OFF'
     >>>
     """
     if isOn:
         return _("ON")
     else:
         return _("OFF")


def _test():
     """_test() perform docstring test"""

     import doctest, teststr
     return doctest.testmod(teststr)

if __name__ == "__main__":
     _test()

#--]-------------------------------------------------


Running the following script shows that the module runs OK:

[Shell buffer started: python.exe]

 >>> import teststr
 >>> import gettext
 >>> gettext.install('impathpl', './locale', unicode=False)
 >>> presLan_en = gettext.translation('impathpl', "./locale", 
languages=['en'])
 >>> presLan_en.install()
 >>> teststr.onOffStr(True)
'ON'
 >>>


BUT, the doctest fails:

D:\dev\python>teststr
*****************************************************************
Failure in example: onOffStr(False)

Exception raised:

I'm still puzzled...
