用tkinter写一个的账本

好的，下面是一个简单的账本程序的Tkinter实现，包含添加记录、显示记录和保存记录的功能。

import tkinter as tk
import json

class AccountBook:
    def __init__(self):
        self.records = []

    def add_record(self, date, category, amount):
        self.records.append({'date': date, 'category': category, 'amount': amount})

    def get_records(self):
        return self.records

    def save_records(self, filename):
        with open(filename, 'w') as f:
            json.dump(self.records, f)

    def load_records(self, filename):
        with open(filename, 'r') as f:
            self.records = json.load(f)

class AccountBookGUI:
    def __init__(self, master, account_book):
        self.master = master
        self.account_book = account_book
        self.master.title('账本')
        self.master.geometry('300x300')

        tk.Label(self.master, text='日期').grid(row=0, column=0)
        tk.Label(self.master, text='类别').grid(row=0, column=1)
        tk.Label(self.master, text='金额').grid(row=0, column=2)

        self.date_entry = tk.Entry(self.master)
        self.category_entry = tk.Entry(self.master)
        self.amount_entry = tk.Entry(self.master)

        self.date_entry.grid(row=1, column=0)
        self.category_entry.grid(row=1, column=1)
        self.amount_entry.grid(row=1, column=2)

        tk.Button(self.master, text='添加记录', command=self.add_record).grid(row=2, column=0)
        tk.Button(self.master, text='显示记录', command=self.show_records).grid(row=2, column=1)
        tk.Button(self.master, text='保存记录', command=self.save_records).grid(row=2, column=2)

    def add_record(self):
        date = self.date_entry.get()
        category = self.category_entry.get()
        amount = self.amount_entry.get()
        self.account_book.add_record(date, category, amount)
        self.date_entry.delete(0, tk.END)
        self.category_entry.delete(0, tk.END)
        self.amount_entry.delete(0, tk.END)

    def show_records(self):
        records = self.account_book.get_records()
        if len(records) == 0:
            tk.messagebox.showinfo('消息', '没有记录')
        else:
            record_info = ''
            for record in records:
                record_info += f'{record["date"]} {record["category"]} {record["amount"]}\n'
            tk.messagebox.showinfo('记录', record_info)

    def save_records(self):
        filename = tk.filedialog.asksaveasfilename(defaultextension='.json')
        if filename:
            self.account_book.save_records(filename)
            tk.messagebox.showinfo('消息', '保存成功')

if __name__ == '__main__':
    account_book = AccountBook()
    root = tk.Tk()
    app = AccountBookGUI(root, account_book)
    root.mainloop()

这个程序使用了两个类，`AccountBook`类表示账本，包含添加记录、显示记录和保存记录的方法，`AccountBookGUI`类是Tkinter的GUI界面，包含添加记录、显示记录和保存记录的按钮。在主程序中创建`AccountBook`对象和`AccountBookGUI`对象，启动GUI界面。通过GUI界面添加账本记录，可以显示和保存记录。

注意，这个程序只是一个简单的示例，可以根据实际需要进行修改和完善。
