If you ever have trouble with an object again, you can use Python's built-in "help" function to obtain details and usage details about the object.

There are many ways to obtain the reverse string sequence of a string, but...

I'm not a Unix user, so please bear with me. As I understand it, in order for the settings you use to be persistent you have to alter your ".profile", but I don't know what that is.
