accesibility of the namespace

In my code I have relatively wide dictionary definition (about 100 rows). I would like to put it in to the different file (module) because of the main code readability (say the name of the file will be "my_dictionary.py") In the dictionary I have strings formatted using % operator like: lcd={2:"Y
