python - 如何识别和区分类名、对象属性和变量、对象方法？

Question

如何识别和区分类名、对象属性和变量、对象方法？太混乱了。。。谁能帮帮我

例如什么是类名？对象属性和变量和对象方法在这里？

def main():
all_vehicles = read_from_file()

frankston_stock.extend(all_vehicles[0])
sunbury_stock.extend(all_vehicles[1])
werribee_stock.extend(all_vehicles[2])

view_menu()

def view_menu():
""""""
menu = "\n"+43*"-"
menu += "\nToyota Car Stock Software \n"
menu +="\n"+43*"-"
menu += "\na. Add a vehicle\n"
menu += "b. Display dealers stock\n"
menu += "c. Remove a vehicle\n"
menu += "d. Save to file\n"
menu += "e. Exit\n"
menu += "Choose Your Choice:\n"
sys.stdout.write(menu)

#
menu_choice = sys.stdin.readline().strip().lower()
if menu_choice == "a":
    add_a_vehicle()
elif menu_choice == "b":
    display_dealer_stock()
elif menu_choice == "c":
    remove_a_vehicle()
elif menu_choice == "d":
    save_to_file()
