rework of a little python-script - extending getters and setters

[snippsat]

thx for the answer - finally got there

You still don't lissen to advice about getters and setters.
If i delete(getters/setters) and do some PEP-8 fixes,30 lines are gone

"""
contacts.py
This program uses a Person class to keep track of contacts.
"""
class Person(object):
    """
    The Person class defines a person in terms of a
    name, phone number, and email address.

    def __init__(self, name, phone, email, padress):

Python Is Not Java

Getters and setters are evil. Evil, evil, I say! Python objects are not Java beans.
Do not write getters and setters.
This is what the 'property' built-in is for. And do not take that to mean that you should write getters and setters, and then wrap them in 'property'.
That means that until you prove that you need anything more than a simple attribute access, don't write getters and setters.
They are a waste of CPU time, but more important, they are a waste of programmer time.
Not just for the people writing the code and tests, but for the people who have to read and understand them as well.
