title: Random quiz generator
body: <p>I have been following an example program from a tutorial book, the program is to take a dictionary with all 50 US states in and their capitals and then to create a random set of multiple choice A-D questions, these questions are then to be randomized and 3 different quizzes printed out into 3 different files. The answers for all the questions for each quiz are then to be printed out into an answers file to go with each questions file.</p>
  
  <p>As a test Im only doing it with a range of 3 for now. When I run the program the files are created but only the 3rd one has the questions in its quiz file and only the 3rd answer file has its answers in too. Files 1 and 2 for the questions have the header section with the blank Name: and Date: but nothing else and their answer files are blank.</p>
  
  <p>I have been over this several times now and can't figure out what the problem is.</p>
  
  <p>Any input would be appreciated, thanks.</p>
