CS106 Summer 2026
Michael Eckmann
Lab 10
July 22, 2026

==================


Purpose:
To get familiar with the following topics

   writing code that reads from a file
   writing code that writes to a file
   writing code that splits a string 
   writing a class that represents an Address

==================

Please read this entire lab file before writing any code.

Write your code in two different python files --- one should contain the class Address and the other the code to read/write a file of addresses

==================

Write a program named reformat.py that reads in a file with lines of the following format:

LastName,FirstName,street address,city,state,zip

And outputs each of those addresses to a file with the addresses of this format:

FirstName LastName
street address
city, state zip

e.g.

Conner,Marc,815 N. Broadway,Saratoga Springs,NY,12866

should be transformed to:

Marc Conner
815 N. Broadway
Saratoga Springs, NY 12866

You may assume that a comma separates each data item and there will be exactly 5 commas on a line.
The input file can contain any number of lines.  Use the names-addresses.txt file posted on the labs page as the input file

--------------------------

Make a class named Address that lives in address.py that has 6 instance variables
and has a constructor and an __str__ method
the __str__ method should return a string of the 3 lines (the reformatted address)

--------

submit to the Spring:

address.py
reformat.py
