Page Generators & CGI

We have seen examples in ThinkPython of python programs that manipulate text.

It is now a small step to changing the output of our program from "plain text" to use some simple markup of HTML.

The next step is CGI!

import cgi

fs = cgi.FieldStorage()
text = fs.getvalue("text", "")

print "Content-type: text/html; charset=utf8"
