You don't have to "put" functions arguments anywhere - they're already 
local vars.

def tokenize(text):
   do some work
   returns or (yields) a list of tokens or whatever

If you want the tokenizer module to work as a self-contained appliction 
*too*, then :

if __name__ == '__main__':
   text = reads the text from a file or stdin
   for token in tokenize(text):
     do something with token
