python实现图书管理系统(带gui)

好的，下面是一个简单的Python图书管理系统的GUI实现示例：

import tkinter as tk
from tkinter import messagebox

class Book:
    def __init__(self, title, author, isbn):
        self.title = title
        self.author = author
        self.isbn = isbn

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

    def load_books(self):
        # 加载已有书籍
        pass

    def add_book(self, book):
        # 添加书籍
        pass

    def remove_book(self, book):
        # 删除书籍
        pass

    def search_book(self, keyword):
        # 搜索书籍
        pass

class Application(tk.Frame):
    def __init__(self, master=None):
        super().__init__(master)
        self.master = master
        self.library = Library()
        self.create_widgets()

    def create_widgets(self):
        self.master.title('图书管理系统')

        # 标签
        self.title_label = tk.Label(self.master, text='书名')
        self.title_label.grid(row=0, column=0)
        self.author_label = tk.Label(self.master, text='作者')
        self.author_label.grid(row=1, column=0)
        self.isbn_label = tk.Label(self.master, text='ISBN')
        self.isbn_label.grid(row=2, column=0)

        # 输入框
        self.title_entry = tk.Entry(self.master)
        self.title_entry.grid(row=0, column=1)
        self.author_entry = tk.Entry(self.master)
        self.author_entry.grid(row=1, column=1)
        self.isbn_entry = tk.Entry(self.master)
        self.isbn_entry.grid(row=2, column=1)

        # 按钮
        self.add_button = tk.Button(self.master, text='添加', command=self.add_book)
        self.add_button.grid(row=3, column=0)
        self.remove_button = tk.Button(self.master, text='删除', command=self.remove_book)
        self.remove_button.grid(row=3, column=1)
        self.search_button = tk.Button(self.master, text='搜索', command=self.search_book)
        self.search_button.grid(row=3, column=2)

        # 列表框
        self.book_listbox = tk.Listbox(self.master, height=10, width=60)
        self.book_listbox.grid(row=4, column=0, columnspan=3)

    def add_book(self):
        title = self.title_entry.get()
        author = self.author_entry.get()
        isbn = self.isbn_entry.get()
        if title and author and isbn:
            book = Book(title, author, isbn)
            self.library.add_book(book)
            self.book_listbox.insert(tk.END, book.title)
            messagebox.showinfo('添加书籍', '添加成功！')
        else:
            messagebox.showerror('添加书籍', '书名、作者和ISBN不能为空！')

    def remove_book(self):
        selection = self.book_listbox.curselection()
        if selection:
            title = self.book_listbox.get(selection[0])
            book = self.library.search_book(title)
            self.library.remove_book(book)
            self.book_listbox.delete(selection[0])
            messagebox.showinfo('删除书籍', '删除成功！')
        else:
            messagebox.showerror('删除书籍', '请选择要删除的书籍！')

    def search_book(self):
        keyword = self.title_entry.get()
        if keyword:
            books = self.library.search_book(keyword)
            self.book_listbox.delete(0, tk.END)
            for book in books:
                self.book_listbox.insert(tk.END, book.title)
        else:
            messagebox.showerror('搜索书籍', '请输入要搜索的关键词！')

root = tk.Tk()
app = Application(master=root)
app.mainloop()

上述代码实现了一个带有GUI界面的图书管理系统。其中，Book和Library类用于表示图书和图书馆，Application类则是GUI程序的主要逻辑实现。在GUI界面中，用户可以输入书名、作者和ISBN，并通过添加、删除和搜索按钮来进行相关操作。同时，程序还会将书籍列表显示在列表框中，方便用户查看已有书籍。
