When you are copy/pasting code, think about how you can make a
function that abstracts the copied bits. For example you could have
player = "/usr/bin/mplayer"
fname = "/home/david/Desktop/core_video/data/" + filename
Then for example you would have
So that is a start. Now look at what you are doing with the individual
sub-lessons. You really just want a way to play a series of lessons.
This can be done with a loop:
files = ['python_0800a.flv', 'python_0801.flv', <snip>, 'python_0806.flv']
for name in files:
Since the lesson names follow a regular pattern you might even be able
to generate the names automatically from the lesson number.
Finally, put a loop in your menu function rather than having the
lessons call back to the menu.
