Hi, So I am writing this small program to determine door access allowed to users.

#create a special no. for storing an RFID card that determines which door I am #allowed to use
door1 = 1
door2 = 2
door3 = 4
door4 = 8
allowed = 0
#add a door or two: for example door 1 and door 3
allowed = allowed|door3
allowed = allowed|door1
print("Access to door 1 is: ", allowed&door1)
print("Access to door 2 is: ", allowed&door2)
print("Access to door 3 is: ", allowed&door3)
print("Access to door 4 is: ", allowed&door4)

The output is:
Access to door 1 is: 1
Access to door 2 is: 0
Access to door 3 is: 4
Access to door 4 is: 0

How can I change from outputting a number to outputting "allowed" and "not allowed" without creating a function to do so.
