title: How to set the program title in python
body: <p>I have been building a large python program for a while, and would like to know how I would go about setting the title of the program? On a mac the title of program, which has focus, is shown in the top left corner of the screen, next the apple menu. Currently this only shows the word &quot;Python&quot;, but I would of course like to my program's title there instead.</p>
