I'm having trouble with 'while' in python

Here is my code:

while c2 != 1 or 2:

    c2 = input('<1.Enter the kitchen> <2.Exit the house> ')

I was trying to make a text-based rpg, but this part kept stuffing up! I wanted the console to keep asking for the input until the 'c2' variable was 1 or 2, but it kept looping! What am I doing wrong?
