When faced with a decision, always ask, 'Which would be the most fun?'

ord() returns the ASCII value of the argument. The ASCII value of 7 is 55. Try doing ord(a) and you should get 97.

There's always a better way. The fun is trying to find it!

 

[arcnon]

characters uses a screen representation called a font to display binary data. So when you are working with characters in like c you could add characters to characters because your adding binary data. And ord is just another representation of binary data. This allows you to work with characters like they are numbers.

Not a masterful explaination but a simple generalization.
