h != "hello" or "goodbye"
is
(h != "hello") or "goodbye"
It's always true because even if (h != "hello") evaluates to False,
then "goodbye" is 'tested' and considered to be true.
You probably meant:
h != "hello" and h != "goodbye"
that can be written even better as:
h not in ("hello", "goodbye")

| In theory, the following code should ask for the user to enter a value for h
| until he/she enters hello or goodbye.
|
| h = "hi"
| while h != "hello" or "goodbye":
| h = raw_input("Value for h:")
|
| But the program keeps asking for a value no matter what I enter. Why doesn't
| it work?
