Getting to know Python

[Arnaldo]

I just downloaded and compiled python in a sunos4.1 OS. I'm starting to have
fun with it but I'm really new
to the language.
I'm planning to buy a book this weekend so I can learn more about python's
syntax and posibly implement some of my c-shell/perl scripts in python.
In the mean-time I'm eager to have with the interactive interpreter.
How do I access the shell from the interpreter to enter commands like
,clear, ls, cp, etc.
Is it posible, how do I do that?

thanks guys
