Re: Running queries on large data structure

Christoph, Well, if you format the data as a Python dictionary and give the data file a .py extension, it becomes a Python module that you can load and reload dynamically. That's sort of what I was thinking. --Dave -- http://mail.python.org/mailman/listinfo/python-list
