python的tinker编写图书管理系统简单程序

好的，下面是一个简单的图书管理系统程序示例，使用 Python 的 Tkinter 模块进行编写：

from tkinter import *
import tkinter.messagebox as messagebox

class Book:
    def __init__(self, name, author, category):
        self.name = name
        self.author = author
        self.category = category

class Library:
    def __init__(self):
        self.books = []

    def add_book(self, book):
        self.books.append(book)

    def remove_book(self, book):
        self.books.remove(book)

    def search_book(self, name):
        for book in self.books:
            if book.name == name:
                return book
        return None

class GUI:
    def __init__(self, library):
        self.library = library
        self.window = Tk()
        self.window.title("图书管理系统")
        self.window.geometry("400x300")
        self.name_label = Label(self.window, text="书名:")
        self.name_label.grid(row=0, column=0)
        self.name_entry = Entry(self.window)
        self.name_entry.grid(row=0, column=1)
        self.author_label = Label(self.window, text="作者:")
        self.author_label.grid(row=1, column=0)
        self.author_entry = Entry(self.window)
        self.author_entry.grid(row=1, column=1)
        self.category_label = Label(self.window, text="分类:")
        self.category_label.grid(row=2, column=0)
        self.category_entry = Entry(self.window)
        self.category_entry.grid(row=2, column=1)
        self.add_button = Button(self.window, text="添加", command=self.add_book)
        self.add_button.grid(row=3, column=0)
        self.remove_button = Button(self.window, text="删除", command=self.remove_book)
        self.remove_button.grid(row=3, column=1)
        self.search_button = Button(self.window, text="搜索", command=self.search_book)
        self.search_button.grid(row=3, column=2)
        self.result_label = Label(self.window, text="")
        self.result_label.grid(row=4, column=0, columnspan=3)

    def add_book(self):
        name = self.name_entry.get()
        author = self.author_entry.get()
        category = self.category_entry.get()
        book = Book(name, author, category)
        self.library.add_book(book)
        self.result_label.config(text="添加成功")

    def remove_book(self):
        name = self.name_entry.get()
        book = self.library.search_book(name)
        if book:
            self.library.remove_book(book)
            self.result_label.config(text="删除成功")
        else:
            self.result_label.config(text="未找到该书")

    def search_book(self):
        name = self.name_entry.get()
        book = self.library.search_book(name)
        if book:
            self.result_label.config(text="书名:{} 作者:{} 分类:{}".format(book.name, book.author, book.category))
        else:
            self.result_label.config(text="未找到该书")

    def run(self):
        self.window.mainloop()

library = Library()
gui = GUI(library)
gui.run()

这个程序实现了添加、删除和搜索图书的功能，使用了面向对象的编程方式，并使用了 Tkinter 模块进行界面设计。用户可以在界面中输入书名、作者和分类，并点击添加、删除和搜索按钮进行操作。程序会根据用户的操作，更新图书馆中的图书，并在界面中显示操作结果。
