for i in list:
    print(i)
def write_selection():
    car_name=input("Enter your selection:")
    selection=""
    list_selection=Cars
    try:
        while selection!="exit":
            selection=input("Enter a new brand:")
    except:
        pass
write_selection()

##The program should ask the user for entering a valid option in our brand list. If the user enter a non-valid option as brand, it should continue forever until a valid option or if s/he enter 'exit'. If the user input is 'exit' display nothing for details.
