Typos Happen
This chapter presents the second of two server-side Python web programming case studies. It covers the design and implementation of PyErrata, a CGI-based web site implemented entirely in Python that allows users to post book comments and error reports, and demonstrates the concepts underlying persistent database storage in the CGI world. As we'll see, this case study teaches both server-side scripting and Python development techniques.
