title: inserting a tuple into a mysql db
body: <p>can anyone show me the syntax for inserting a python tuple/list into a mysql database?
  i also need to know if it is possible for user to pass certain rows without inserting anything...
  for example: a function is returning this tuple:</p>
  
  <pre><code>return job(jcardnum, jreg, jcarddate, jcardtime, jcardserve, jdeliver)
  </code></pre>
  
  <p>suppose the user didnt enter anything in <code>jreg</code>
  would python itself enter null in to the related row in the DB or would i run in to trouble?</p>
