Hello all,

I have used *args and **kwargs to have a function accept optional parameters, but is there a lazy way to optionally pass parameters? For example, say my script can accept a number of parameters for a database connection, such as user, password, and database name. The function that makes the MySQL call has a default for user, say "root". So if the user didn't pass in a value for the user option, I don't want to pass it to the function doing the MySQL call. I don't want to have to do:

if options.user: 

and so on for each possible option. Is there a better way?
