Answer 1

You can use not logic to check if board_size is equal to 3, 5, or 7. You can use sys.exit() to exit the program, but make sure to import sys.

import sys

def main():
    
    while True:    
        board_size = int(input("How big playing surface (3/5/7)? "))
        
        if not (board_size == 3 or board_size == 5 or board_size == 7):
            sys.exit()
        else:
            break
    while True:
        games = int(input("How many games do you want to simulate? "))

        if games <1:
            sys.exit()
        else:
            break

    while True:
        scenario = int(input('What scenario (1/2)? '))

        if not (scenario == 1 or scenario == 2):
            sys.exit()
        else:
            break

    print(games, scenario, board_size)

main()
