写一个pycharm图书管理系统编码

以下是一个简单的图书管理系统的Python代码示例，使用PyCharm编写：

# 图书管理系统

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

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, title):
        for book in self.books:
            if book.title == title:
                return book

    def display_books(self):
        for book in self.books:
            print(book.title, book.author, book.isbn, book.year)

# 测试
library = Library()

book1 = Book("Python for Everybody", "Charles Severance", "978-1530051120", 2016)
book2 = Book("Automate the Boring Stuff with Python", "Al Sweigart", "978-1593275990", 2015)

library.add_book(book1)
library.add_book(book2)

print("所有图书信息：")
library.display_books()

print("查找Python for Everybody书籍：")
book = library.search_book("Python for Everybody")
print(book.title, book.author, book.isbn, book.year)

print("删除Automate the Boring Stuff with Python书籍：")
library.remove_book(book2)

print("所有图书信息：")
library.display_books()

这段代码实现了一个简单的图书管理系统，其中有两个类：Book和Library。Book类表示一本书，包含标题、作者、ISBN号和出版年份。Library类表示图书馆，包含一组书籍，可以添加、删除、查找和显示这些书籍。在测试部分，我们创建了两本书并添加到图书馆中，然后查找并显示其中一本书的信息，最后删除另一本书并显示所有书籍的信息。
