Python实现可以输入事件，并且赋予事件重要程度，按照事件重要程度存储事件，删除事件，修改事件，制定事件完成时间的记事本的代码最后生成txt

好的，我可以为您编写这个记事本的代码。以下是Python实现可以输入事件，并且赋予事件重要程度，按照事件重要程度存储事件，删除事件，修改事件，制定事件完成时间的记事本的代码：

import datetime

class Event:
    def __init__(self, name, importance, deadline=None):
        self.name = name
        self.importance = importance
        self.deadline = deadline

    def __repr__(self):
        return f"{self.name} (Importance: {self.importance}, Deadline: {self.deadline})"

class Notes:
    def __init__(self):
        self.events = []

    def add_event(self, name, importance, deadline=None):
        event = Event(name, importance, deadline)
        self.events.append(event)
        self.sort_events()

    def delete_event(self, index):
        self.events.pop(index)

    def modify_event(self, index, name=None, importance=None, deadline=None):
        event = self.events[index]
        if name:
            event.name = name
        if importance:
            event.importance = importance
        if deadline:
            event.deadline = deadline
        self.sort_events()

    def sort_events(self):
        self.events.sort(key=lambda x: x.importance, reverse=True)

    def print_events(self):
        for i, event in enumerate(self.events):
            print(f"{i+1}. {event}")

    def save_to_file(self, filename):
        with open(filename, "w") as f:
            for event in self.events:
                deadline_str = event.deadline.strftime("%Y-%m-%d") if event.deadline else ""
                f.write(f"{event.name},{event.importance},{deadline_str}\n")

    def load_from_file(self, filename):
        with open(filename, "r") as f:
            for line in f:
                line = line.strip()
                if line:
                    name, importance, deadline_str = line.split(",")
                    importance = int(importance)
                    deadline = datetime.datetime.strptime(deadline_str, "%Y-%m-%d") if deadline_str else None
                    self.add_event(name, importance, deadline)

notes = Notes()

while True:
    print("1. Add Event")
    print("2. Delete Event")
    print("3. Modify Event")
    print("4. Print Events")
    print("5. Save to File")
    print("6. Load from File")
    print("7. Exit")
    choice = int(input("Enter your choice (1-7): "))

    if choice == 1:
        name = input("Enter event name: ")
        importance = int(input("Enter event importance (1-10): "))
        deadline_str = input("Enter event deadline (YYYY-MM-DD, leave blank if none): ")
        deadline = datetime.datetime.strptime(deadline_str, "%Y-%m-%d") if deadline_str else None
        notes.add_event(name, importance, deadline)
    elif choice == 2:
        notes.print_events()
        index = int(input("Enter event index to delete: ")) - 1
        notes.delete_event(index)
    elif choice == 3:
        notes.print_events()
        index = int(input("Enter event index to modify: ")) - 1
        name = input("Enter new event name (leave blank if no change): ")
        importance = input("Enter new event importance (leave blank if no change): ")
        deadline_str = input("Enter new event deadline (YYYY-MM-DD, leave blank if no change): ")
        deadline = datetime.datetime.strptime(deadline_str, "%Y-%m-%d") if deadline_str else None
        notes.modify_event(index, name, importance, deadline)
    elif choice == 4:
        notes.print_events()
    elif choice == 5:
        filename = input("Enter filename to save to: ")
        notes.save_to_file(filename)
    elif choice == 6:
        filename = input("Enter filename to load from: ")
        notes.load_from_file(filename)
    elif choice == 7:
        break
    else:
        print("Invalid choice, please try again.")

这个记事本可以让您输入事件名称、重要程度和截止日期，并按照重要程度排序。您可以使用菜单选项添加、删除、修改、打印、保存和加载事件。当您选择保存选项时，所有事件将保存到指定的文件中。当您选择加载选项时，程序将从指定的文件中加载事件。
