here's the documentation for the regular reader, from Python 2.5:
csv_reader = reader(iterable [, dialect='excel']
[optional keyword args])
for row in csv_reader:
The "iterable" argument can be any object that returns a line
of input for each iteration, such as a file object or a list.
so the reader is simply looping over the characters in your filename. try
r = csv.DictReader(open('C:\Temp\Book1.csv'))
