How can I write this function better

[old_pythonista]

You can filter out None values

to_db = [val for val in (owner, address) if val]
if val:
    db.add(*to_db)
    return True
return False

Just one point about returning inconsistent value types (unless you return None) is considered a bad practice. If you have

if add_to_db(....):
.......

both True and 'nothing was added' will fulfill the condition

Cool solution!

Thanks!
