Usage

• The README contained everything I needed to easily use the program:

  It appears that many of the problems earlier reviewers mentioned were resolved, though the run instructions would be clearer in a code block as an actual command example.

• The program compiles/runs without errors:

  Glad to see a sample data file was provided in response to the earlier reviews!

• The program worked as advertised:

Style

• The code is cleaning divided into modules and multiple files:

• Variable and function names are meaningful:

• Comments are used where appropriate:

  While the class and method names were easy to understand use of docstrings would allow for automatic documentation generation.

Philosophy

• The program most closely follows the ed-like interface pattern:

• This choice of pattern is a good one for this application:

• This program follows the Rule of Silence and Least Surprise:

  I would have expected, and it would increase the scriptability, if all paramters could be given in a command, rather than being prompted for them. For example, I would like to be able to run edit <last name> set_home_phone 555-123-0987

• This program follows the Rules of Modularity and Composition:

  composability could be greatly increased if commands could be given on standard input

• This program follows the Rules of Representation and Simplicity:

  flexibility could be greatly improved if keys were just grabbed from the data file itself. Rather than hardcoding first, last, home, etc. perhaps define a couple required keys (like first and last) but then just use whatever the data file provides for the rest.
