capitals = ["Lisbon", "Madrid", "Paris", "Berlin", "London",

client_name = "Me" 
while True: 
    answer = input(client_name + ": ") 
    if answer == "What is the capital of Germany?": 
     print(capitals[3]) 
    else: 
     print("I don't understand!") 

Answer 2

    answer = input(client_name + ": ") 
    if answer == "What is the capital of Germany?": 
     print(capitals[3]) 
    else: 
     print("I don't understand!")
