[i18n] Multilang. app in Python (English, French, German)?

[F. GEIGER]

Is there a way to do this in a professional manner?

For now I only can think of having all strings in a file, read them into 
a dict at startup and then access them like so:

print str(MyTextDict('e', "errorOnDbStore"))

or

print str(MyTextDict('f', MyTextDict._ErrorKey_ErrorOnDbStore))

Is it this or is there a "more Pythonic" way?

Kind regards
Franz GEIGER

P.S.: I'm on Windows and use wxPython for the GUI part. I intend to be 
able to select the language in an INI file before starting the app.
