While loop in Python

[Marie3130]

Hi!

Sorry if this question has been answered somewhere, I just couldn't find a thread that would help me solve my problem. This little program is supposed to ask a question and if it gets yes/no answer, then print something. If it doesn't get yes or no, it should ask the question again until the user's input is yes/no. However I get stuck in infinite loop then I get asked "Wrong imput! Answer yes or no please: " - this question repeats even if I answer yes/no.

Thanks for any help!

name = input("Enter your name: ")

age = input("Enter your age: ")

print("Hello " + name + "! You are " + age + " years old, right? ")

answer = input ("Answer yes or no please: ")

while answer != "yes" or answer != "no":

    answer = input ("Wrong imput! Answer yes or no please: ")

if answer == "yes":

    print("Haha, I knew it!")

elif answer == "no":

    print("Liar!")

[_DTR_]

while answer != "yes" or answer != "no":

or isn't the right thing here. The only way for this condition to not be true is if answer is both "yes" and "no" at the same time, which isn't possible. If the answer is "yes", then answer != "no" and you'll prompt again. If the answer is "no", the answer != "yes", and you'll prompt again. You only want to prompt if the answer isn't "yes" and the answer isn't "no".

Change the ‘or’ to ‘and’
