def automotive_service():
    print("To select service from the menu type service name. If you don't want to select any service you can enter -.");
    service1 = input("Select first service: ").lower();
    service2 = input("Select second service: ").lower();

    if service1 not in services.keys() or service2 not in services.keys():
        print("Please enter valid service from menu")
        automotive_service()
    else:
        if service1 == '-':
            print('Service 1: No service');
        else:
            print('Service 1: ' + service1 + ', $' + services[service1]);
        if service2 == '-':
            print('Service 2: No service');
        else:
            print('Service 2: ' + service2 + ', $' + services[service2]);
        total = int(services[service1]) + int(services[service2])
        print("Total: $" + str(total));


if __name__ == '__main__':
    print("Davy'a auto shop services");
    print("Oil change -- $35 \nTire rotation -- $19 \nCar wash -- $7 \nCar wax -- $12");
