Newbie's Questions

[Thomas Guettler]

Yesterday I had time to start learning python. I like it, after a half
hour I wasn't missing the "{..}" anymore. Here are some questions I
have:

Is there a way of checking the program when I start it.  So typos are
detected emidiately, and not when I enter the function.

Is there something like "use strict" in perl? I like to declare my
variables before I use them. (Again, to recognize typos)

Is there a way of reading a single character from stdin without
waiting for the return-key? (At best without curses)

Is there something like "exit" in C? Yes, I could just raise an
exception, but I prefere a way without a stacktrace.
