用tkinter写一个能查询的账本

好的，下面是一个简单的例子，可以创建一个带有查询功能的账本：

import tkinter as tk
import csv

root = tk.Tk()
root.title("账本")

# 读取csv文件并创建初始交易记录
transaction_list = []
with open("transactions.csv", "r") as f:
    reader = csv.reader(f)
    for row in reader:
        transaction_list.append(row)

# 定义函数
def add_transaction():
    amount = float(amount_entry.get())
    transaction_type = type_var.get()
    transaction_list.append([transaction_type, amount])
    update_display()

def update_display():
    balance = 0
    transaction_text.delete("1.0", tk.END)
    for transaction in transaction_list:
        if transaction[0] == "收入":
            balance += transaction[1]
        else:
            balance -= transaction[1]
        transaction_text.insert(tk.END, "{}: ￥{:.2f}\n".format(transaction[0], transaction[1]))
    balance_label.config(text="余额：￥{:.2f}".format(balance))

def search_transaction():
    keyword = search_entry.get().strip()
    if keyword:
        search_result = []
        for transaction in transaction_list:
            if keyword in transaction[0]:
                search_result.append(transaction)
        transaction_text.delete("1.0", tk.END)
        for transaction in search_result:
            transaction_text.insert(tk.END, "{}: ￥{:.2f}\n".format(transaction[0], transaction[1]))
    else:
        update_display()

def save_transaction():
    with open("transactions.csv", "w", newline="") as f:
        writer = csv.writer(f)
        writer.writerows(transaction_list)

# 创建组件
amount_label = tk.Label(root, text="金额：")
amount_entry = tk.Entry(root, width=10)
type_label = tk.Label(root, text="类型：")
type_var = tk.StringVar()
type_var.set("收入")
type_menu = tk.OptionMenu(root, type_var, "收入", "支出")
add_button = tk.Button(root, text="添加", command=add_transaction)
balance_label = tk.Label(root, text="余额：￥0.00")
search_label = tk.Label(root, text="查询：")
search_entry = tk.Entry(root, width=10)
search_button = tk.Button(root, text="搜索", command=search_transaction)
transaction_text = tk.Text(root, height=10, width=30)
save_button = tk.Button(root, text="保存", command=save_transaction)

# 布局组件
amount_label.grid(row=0, column=0)
amount_entry.grid(row=0, column=1)
type_label.grid(row=0, column=2)
type_menu.grid(row=0, column=3)
add_button.grid(row=0, column=4)
balance_label.grid(row=1, column=0, columnspan=5)
search_label.grid(row=2, column=0)
search_entry.grid(row=2, column=1)
search_button.grid(row=2, column=2)
transaction_text.grid(row=3, column=0, columnspan=5)
save_button.grid(row=4, column=4)

# 初始化显示
update_display()

# 运行程序
root.mainloop()

这个例子和之前的例子类似，但增加了查询和保存功能。用户可以输入关键词进行查询，查询到的交易记录会显示在Text控件中。点击“保存”按钮，程序会将交易记录保存到csv文件中。
