you may be misreading the docs; the Dialect has no values at all, and
must be subclassed (and the subclass must provide settings). The
easiest way to do get reasonable defaults is to subclass an existing
dialect class, such as csv.excel:
class dialect(csv.excel):
...

the source code for the Dialect class that you posted shows how to set
class attributes; simple assign them inside the class statement!
class dialect(csv.excel):
# like excel, but with a different delimiter
delimiter = "|"
you must also remember to pass the dialect to the reader:
reader = csv.reader(open('list.csv'), dialect)
for row in reader:
print row
note that you don't really have to create an instance; the reader
expects an object with a given set of attributes, and the class object
works as well as an instance of the same class.
