using yaml for persistence

[paul jobs]

class User(object):

    def __init__(self, uid):

       self.uid = uid

       self.__dict__.update(yaml.load(str('uid')+'.yaml'))

 

    def save(self):

        f=open(str(self.uid)+'.yaml')

        yaml.dump(self.__dict__, f)

 

 

 

is there a better way to persist using Yaml
