Python无循环/函数实现点餐系统（含酱料选择）问题求助

代码实现 #

# 显示餐品菜单
print("请选择餐品：")
print("1 - Steak（牛排）")
print("2 - Mussels（贻贝）")
print("3 - Scampi（炸虾球）")
print("4 - Quinoa（藜麦）")

# 获取用户餐品选择
meal_choice = input("输入对应数字：")

# 转换为整数并处理非数字输入
try:
    meal_num = int(meal_choice)
except ValueError:
    print("We do not serve this")
else:
    # 判断餐品选择是否合法
    if meal_num == 1:
        meal_name = "Steak（牛排）"
        # 显示牛排酱料选项
        print("\n请选择酱料：")
        print("1 - 黑胡椒酱")
        print("2 - 蘑菇酱")
        print("3 - 红酒酱")
        sauce_choice = input("输入对应数字：")
        
        try:
            sauce_num = int(sauce_choice)
            if sauce_num == 1:
                sauce_name = "黑胡椒酱"
            elif sauce_num == 2:
                sauce_name = "蘑菇酱"
            elif sauce_num == 3:
                sauce_name = "红酒酱"
            else:
                print("无效酱料选择，默认搭配黑胡椒酱")
                sauce_name = "黑胡椒酱"
        except ValueError:
            print("无效酱料选择，默认搭配黑胡椒酱")

        print("1 - 柠檬黄油酱")
        print("2 - 番茄蒜蓉酱")
        print("3 - 白葡萄酒酱")
        sauce_choice = input("输入对应数字：")
        
        try:
            sauce_num = int(sauce_choice)
            if sauce_num == 1:
                sauce_name = "柠檬黄油酱"
            elif sauce_num == 2:
                sauce_name = "番茄蒜蓉酱"
            elif sauce_num == 3:
                sauce_name = "白葡萄酒酱"
            else:

        # 显示炸虾球酱料选项
        print("\n请选择酱料：")
        print("1 - 塔塔酱")
        print("2 - 甜辣酱")
        print("3 - 蒜蓉蛋黄酱")
        sauce_choice = input("输入对应数字：")
        
        try:
            sauce_num = int(sauce_choice)

    elif meal_num == 4:
        meal_name = "Quinoa（藜麦）"
        print(f"\n您的餐品：{meal_name}")
    
    else:
        print("We do not serve this")

代码说明 #

• 用try-except捕获用户输入非数字的情况，避免程序崩溃，同时输出指定提示
• 每个餐品选择用独立的if-elif分支处理，完全符合禁止使用循环和函数的要求
• 前3款餐品分支内嵌套酱料选择的判断逻辑，同样用try-except和if-elif处理非法输入，默认分配一款酱料
• 非法餐品数字直接输出We do not serve this
• 输出格式清晰，明确展示最终的餐品+酱料组合
