But the question is, where are the rules for this?  For instance, if I type the following in a PY file, it errors out and I don't see the DOS window with the output in Vista:

It’s called the command prompt.

You indented the wrong thing.  You put your if/else statement in a
non-standard way (which works, but is discouraged).  Also, you ended
the first line with a semicolon (same case).  So, the proper code
would be:

a=1
if a==1:
    print(1)
else:
    print(0)
wait = input("press key")

(I resisted the urge to add spaces around `=` and `==`, something most
people want you to do.)
