Using the Quiz System

Components

• question_entry.py: Allows guided data entry of questions and answers for a particular chapter and section.
  Each project will have a script called qentry.sh that will run the Python script with proper parameters and do the follow-up steps necessary: if you are on Windows, you can always look at the script and do these steps manually. And someone could create a PowerShell script to do the same steps...
• quiz2html.py: Takes the delimited text files (CSV files, but we aren't using commas as separators!) and turns them into html code for inclusion in a web page.
  Run it like: ../utils/quiz2html.py quiz1.1.txt > quiz1.1.qhtm
  But, you should not have to run this by hand! Use the makefile in the quizzes directory.
  But, better yet, you shouldn't even have to do that by hand... qentry.sh runs make for you.
• quiz2test.py: Takes the delimited text files (CSV files, but we aren't using commas as separators!) and turns them into stand-alone files suitable for printing as a test.
• html_include.awk: Reads the quizzes into the appropriate web pages. You will need to enter an include statement in the proper place in a *.ptml file, like this (take out the slashes when you use this):
  \<\!--include quiz6.2.qhtm -->
• qexport.py: Exports quiz content from the database and prints it on screen. The database configurations are set in mysite/settings.py. Quiz material for different modules can be filtered by calling qexport.py <module_name>
• qimport.py: Reads a file provided as input and writes them to the database.
• qexport.sh: Shell script which set database configurations to prod DB and calls qexport.py. This script is encrypted using git-crypt for safe keeping of the database credentials.

A run of the question entry system

        
Macintosh:algorithms gcallah$ ./qentry.sh
Enter chapter # for question: 4
Enter section # for question: 5
Enter question (blank to stop entering): Using master method (mm), the runtime
for T(n)=3T(n/2)+n2 is:
Enter correct answer (we will randomize for you!): Θ(n2)
Enter a wrong answer (blank to stop entering): Θ(n3/2)
Enter a wrong answer (blank to stop entering): n log n
Enter a wrong answer (blank to stop entering): MM does not apply
Enter a wrong answer (blank to stop entering):
Enter question (blank to stop entering): Using mm, the runtime for T(n) - 2n(n/2) + nn is:
Enter correct answer (we will randomize for you!): MM does not apply
Enter a wrong answer (blank to stop entering): Θ(2n)
Enter a wrong answer (blank to stop entering): Θ(nn)
Enter a wrong answer (blank to stop entering): Θ(n)
