Sometimes, you might want to validate the user input and continue asking for input until you get a valid response. Example (Taking an integer as input): while True: user_input = input("Enter a number (or 'exit' to stop): ") if user_input == 'exit': break if user_input.isdigit()...

Main program loop. while True: # Keep asking until the user enters valid input. print('Enter the Nth Fibonacci number you wish to') print('calculate (such as 5, 50, 1000, 9999), or QUIT to quit:') response = input('> ').upper() if response == 'QUIT': print('Thanks for ...

Typically, we perform input validation by repeatedly asking the user for input until they enter valid text, as in the following example: while True: print('Enter your age:') age = input() try: age = int(age) except: print('Please use numeric digits.') continue if age < 1: print('...

"" while True: # Keep asking player until they enter a valid move. print(f"Player {playerTile}, enter 1 to {BOARD_WIDTH} or QUIT:") response = input("> ").upper().strip() if response == "QUIT": print("Thanks for playing!") sys.exit() if response not in COLUMN_LABELS: ...
