I see the basic problem as this: - you have config settings (command line options, config files) which by their nature are always strings - furthermore they are strings in a format designed for human use rather than machine use - by the time your function uses them, they need to be converted from human-format to machine-format. That last step might involve a type conversion like int(s), trimming whitespace, or more complex operations. The most obvious way to do them is to apply the operation after reading the config value but before storing it in the params dict. If that works, I wouldn't add complexity where it isn't needed. If it doesn't work for you, I think you need to explain what the problem is before we can suggest a better design. -- Steve _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
