mutiple or conditions on a While loop in python in python

Have forgotten how to declare multiple conditions on a while loop

Its going to take one of the input and check the user has entered either of the 4 correct letters. Currently however, it always drops into the loop

temp = input()
while temp.lower() != ("a" or "b" or "c" or "d"):
    print("Error, you must enter either A, B, C or D")
    print(inventory())
    print("What would you like to buy?")
    temp = input()

You might want to consider

while temp.lower() not in ('a','b','c','d'):
    print("Error")

Don't know why one would do this but still here's an option:

import string
while temp.lower() not in string.ascii_lowercase[:4]:
    print("Error")

Explicitely you would have to write

while (temp.lower() != "a") and (temp.lower() != "b")....... :

but you might want to try

while temp.lower()[0] not in 'abcd':

However, note the indexing I added here to the lowered input variable, as otherwise substrings of 'abcd' of length > 1 would match, too.
