I go into ~/apache/cgi-bin/ and create a folder 0707.

I move into it and create two files: template.py, one. 

We developed a template: 

import cgi

class Engine(object):
  def __init__(self): 
    self.input = cgi.FieldStorage()
  def start(self):
    state = self.retrieveState()
    if state.isEmpty():
      self.initializeState(state)
    else:
      self.updateState(state)
    self.reportState(state)
    self.saveState(state)
    self.getReadyforMoreInput()
  def retrieveState(self):        return State()
  def initializeState(self, s):   pass
  def updateState(self, s):       pass
  def reportState(self, s):       pass
  def saveState(self, s):         pass
  def getReadyforMoreInput(self): pass

class State(object):
  def isEmpty(self):
    return True

And we started developing a driver:

#!/usr/bin/python

import template, random

class Driver(template.Engine):
  def __init__(self):
    template.Engine.__init__(self)
  def retrieveState(self):
    # print self.input
    return template.State()
  def reportState(self, s):
    print"Content-type: text/html\n\n"
    print self.input  

a = Driver()
a.start()

I made the second program executable and called it:
