Help for the simple terminal in phyton

Hello I want to create a simple terminal to ask the user "Are you ready?" 1- If user entered "Y" then terminal show the question 2- If user entered "N" then terminal finish 3 - If user entered any other word terminal show "Please enter Y or N" and ask the question again. I write it like below but it always says the "Please enter Y or N" print("So, Are you ready for the game?") print("Y=Yes N=No") answer = input() while answer != "Y" or answer != "N": print("Please enter Y or N") answer = input() if answer == "Y": print("Great! Lets start") if answer == "N": print("Come back when you were ready")

Mohammad Razavi , > the issue is the current logical expression, so lets fix this. here you can see how the evaluation of the expression is: if input => Y answer = 'Y', answer != "Y" = False, answer != "N" = True, answer != "Y" or answer != "N" = True if input => N answer = 'N', answer != "Y" = True, answer != "N" = False, answer != "Y" or answer != "N" = True if input = X answer = 'X', answer != "Y" = True, answer != "N" = True, answer != "Y" or answer != "N" = True since we are using a logical *or*, the result of the expression will be True if one of the parts is True. > so what ever character we input, the complete expression will be true (which is while True: => infinite loop) > to fix it we can use this: while answer not in 'YN': ... or this: while not (answer == 'Y' or answer == 'N'): ... https://code.sololearn.com/cAhdevvav4pF/?ref=app

I would put if statements inside the loop

The user must capitalize his or her answer before the code can validate it

You could add answer=answer.upper() after your input() statement.

Lamron Thanks! It worked but still have problem. When i put the if statements inside the while loop user have to press Y or N twice. First time terminal shows "Please enter Y or N" but at second try it works well.

It is best you use a loop for this so that your code does not look too messy and you are able to call back later while True : response1 = input("Y=Yes N=No : ") if response1 == "Y" : print("Great! Lets start") elif response1 == "N" : print("Come back when you were ready") break else : print("Please enter a valid input :(") So this loops keeps asking tho😂😂

while True: command = input("Enter a command: ") if command == "exit": print("Exiting the terminal.") break print(f"You entered: {command}")
