Having a snippet like this:

import yaml
class User(object):
    def __init__(self, name, surname):
       self.name= name
       self.surname= surname

user = User('spam', 'eggs')
serialized_user = yaml.dump(user)
deserialized_user = yaml.load(serialized_user)
print "name: %s, surname %s" % (deserialized_user.name, deserialized_user.surname)

Yaml docs says that it is not safe to call yaml.load with any data received from an untrusted source; so, what do i need to modify to my snippet\class to use safe_load method?
Is it possible?
