I want a parse a file of the format: movieId customerid, grade, date customerid, grade, date customerid, grade, date etc.
so I could do with open file as reviews and then for line in reviews. but first I want to take out the movie id so I use an iterator. then i want to iterate through all the rows, but how can I do: while movie_iter != None: because that doesn't work, itraises an exception, StopItreation, which according to the documentation it should. But catching an exception can't be the standard way to stop iterating right? -- http://mail.python.org/mailman/listinfo/python-list
