Obviously the statement (well, "test") isn't false! Let's look:
>answer8 = ""
>while answer8 != ("1") or answer8 != ("2"):
Answer8 cannot be both "1" and also "2". Therefore, it will always _not_ be
equal to at least one of "1" and "2". Therefore this test is always true.
You might better write this:
while answer8 not in ("1", "2"):
while not( answer8 == "1" or answer8 == "2" ):
BTW, you need to decide whther you're working in strings or integers. input()
in Python 3 returns a string. If you want to test against strings, fine.
However, if you want to test against numbers you need to convert the string to
answer8n = int(answer8)
and then test against answer8n.
