How to Ask for User Input in Python Until a Valid Response is Given?

Estimated read time 2 min read

In Python, you can use a loop to ask for user input until a valid response is given. One way to do this is to use a while loop with a condition that checks whether the input is valid or not. Here’s an example:

while True:
    user_input = input("Please enter a valid response: ")
    if user_input == "valid":
        print("Thank you for your valid response!")
        break  # Exit the loop
    else:
        print("Sorry, that is not a valid response. Please try again.")

In this example, the while loop will continue to run until a valid response is given. The condition in the while loop is set to True, so the loop will continue to run indefinitely until the break statement is encountered. The user is prompted to enter a response using the input() function. If the user’s input matches the valid response, the loop is exited using the break statement. If the user’s input is not valid, the loop continues to run and the user is prompted to try again.

You can modify this example to suit your specific requirements. For example, you can use a list or a set to store valid responses and check whether the user’s input is in that list or set.
