I read the documentation and encountered this:

return address

What are the key and address in the validate_address function? I can't
find any explanation in our documentation. Do they have any meaning or
expect any special objects? Can I use other names for those two
parameters here? Thanks.
assuming you are reading
http://docs.sqlalchemy.org/en/rel_1_0/orm/mapped_attributes.html?highlight=validates#simple-validators,
that *is* the documentation...."address" is the value that's being
validated and "key" is the name of the attribute being altered, in this
case "addresses". the parameters are positional.
