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.)
