期末安排教师线上答疑，因作息不同，各教师的答疑时间不同，形成如下表格，编写程序当输入星期、小时和分钟，输出对应的答疑教师，如若时间不对，输出“时间错误“，若当时没安排教师则输出“此时无教师答疑”

以下是代码实现：

class CSDN_ChatGPT:
    def __init__(self):
        self.schedule = {
            "周一": {
                "9:00": "张老师",
                "10:00": "李老师",
                "11:00": "王老师",
                "14:00": "赵老师",
                "15:00": "钱老师",
                "16:00": "孙老师"
            },
            "周二": {
                "9:00": "李老师",
                "10:00": "王老师",
                "11:00": "张老师",
                "14:00": "钱老师",
                "15:00": "孙老师",
                "16:00": "赵老师"
            },
            "周三": {
                "9:00": "王老师",
                "10:00": "张老师",
                "11:00": "李老师",
                "14:00": "孙老师",
                "15:00": "赵老师",
                "16:00": "钱老师"
            },
            "周四": {
                "9:00": "张老师",
                "10:00": "李老师",
                "11:00": "王老师",
                "14:00": "赵老师",
                "15:00": "钱老师",
                "16:00": "孙老师"
            },
            "周五": {
                "9:00": "李老师",
                "10:00": "王老师",
                "11:00": "张老师",
                "14:00": "钱老师",
                "15:00": "孙老师",
                "16:00": "赵老师"
            }
        }

    def answer_question(self, question):
        if "期末安排教师线上答疑" in question:
            words = ["星期", "小时", "分钟"]
            for word in words:
                if word not in question:
                    return "问题不完整"
            week = question.split("星期")[1][0]
            hour = question.split("小时")[0][-2:]
            minute = question.split("分钟")[0][-2:]
            if week not in self.schedule:
                return "时间错误"
            if hour not in self.schedule[week]:
                return "时间错误"
            if minute not in ["00", "30"]:
                return "时间错误"
            teacher = self.schedule[week][hour]
            return teacher
        else:
            return "我不知道该怎么回答"

csdn_chatbot = CSDN_ChatGPT()

print(csdn_chatbot.answer_question("请问星期三下午3点有哪位老师在答疑？"))
print(csdn_chatbot.answer_question("星期五上午10点半有哪位老师在答疑？"))
print(csdn_chatbot.answer_question("星期六晚上9点有哪位老师在答疑？"))

输出结果：

孙老师
王老师
