9 encrypt = input("Enter E to encrypt, D to decrypt, and Q to quit: ")
10 print(encrypt)
11 while encrypt.lower() != "e" or "d" or "q":
12 encrypt = input("Please try again with a valid input (E, D, or Q): ")
13 print(encrypt)
14
15 if encrypt.lower() == "q":
16 sys.exit()
I have this loop to continue looking for input until it's either e, d, or q. When I run it, no input triggers to leave the loop, even if it's one of those three characters. The only thing I can do to get out of the program period is to input an EOF error. I'm sure it's something stupid I'm doing wrong but I can't find anything syntactically wrong, I'm not getting any errors, and I'm not even using any extra libraries past what's built in to python 3. Any clues?
