A small correction to my code, although the point was hopefully still clear:
if options.user:
do_mysql_query(options.user)
else:
do_mysql_query()

Subject: [Tutor] Optional parameter passing
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:
do_mysql_query(user)
else:
do_mysql_query()
and so on for each possible option. Is there a better way?
Thanks,
Sam
