Using Classes problem

If a student writes:

<pre>
def print_friend_info(person):
    print(person._name)
    print(person._age)
    if self._friend is not None:
        print('Friends with', person._friend._name)
</pre>

then there is an error  "You need to print the person's name in print_friend_info"

The error should really be about not using the getters such as person.get_name()
