Classes have a dictionary that only contains the methods and class
members. Class _instances_ have a __dict__ that contains the data

It does -- it is part of the data.

The same way you always do. Here's an example (that skips the file
read/write step) :
class C :
o = C()
o.foo = "bar"
o.spam = "eggs"
pickled_string = pickle.dumps( o )
# normally you would write this string to a file, or a socket, or something
del o # just to make sure the old one is gone and I can't make a typo
# normally you would read the string from a file, or a socket, or something
obj = pickle.loads( pickled_string )
print obj.foo , obj.spam
