【禁止废话】python图书管理系统代码（最简单的功能实现）

一、创建类Book和Library，编写函数。

名称，编号，价格，简介。

class Book:
    def __init__(self, booknu, bookname, bookprice, booksumary):
        self.booknu = booknu
        self.bookname = bookname
        self.bookprice = bookprice
        self.booksumary = booksumary


class library:
    def __init__(self):
        self.booklist = []

    def addbook(self, book):
        self.booklist.append(book)

    def deletebook(self, booknu):
        for book in self.booklist:
            if book.booknu == booknu:
                self.booklist.remove(book)

    def updatebook(self, booknu, bookprice):
        for book in self.booklist:
            if book.booknu == booknu:
                book.bookprice = bookprice

    def findbook(self, name):
        resultlist = []
        for book in self.booklist:
            if book.bookname.find(name) >= 0:
                resultlist.append(book)
            else:
                print("Don't find the book.")

    def showbook(self, booknu):
        if self.booklist:
            print("The book list")
            for book in self.booklist:
                print(book.booknu, book.bookname, book.bookprice, book.booksumary)
        else:
            print("There nothing in the library.")

二、函数调用。

包括输入书籍、删除书籍、更新书籍、查找书籍和展示书籍。

li = library()
while True:
    print("\naddbook(1)")
    print("deletebook(2)")
    print("updatebook(3)")
    print("findbook(4)")
    print("showbook(5)")
    print("outbook(6)")
    action = input("请输入操作编号（1-6）:")
    if action == '1':
        booknu = int(input("输入书号: "))
        bookname = input("输入书名: ")
        bookprice = float(input("输入价格: "))
        booksumary = input("输入摘要: ")
        new_book = Book(booknu, bookname, bookprice, booksumary)
        li.addbook(new_book)

    elif action == '2':
        booknu = input("请输入图书编号：")
        li.deletebook(booknu)
        li.showbook()

    elif action == '3':
        booknu = input("请输入图书编号：")
        bookprice = input("请输入图书价格：")
        li.updatebook(booknu,bookprice)
        li.showbook()

    elif action == '4':
        bookname = input("请输入图书名称：")
        li.findbook(bookname)

    elif action == '5':
        li.showbook()

    elif action == '6':
        break

三、总代码展示。

class Book:
    def __init__(self, booknu, bookname, bookprice, booksumary):
        self.booknu = booknu
        self.bookname = bookname
        self.bookprice = bookprice
        self.booksumary = booksumary


class library:
    def __init__(self):
        self.booklist = []

    def addbook(self, book):
        self.booklist.append(book)

    def deletebook(self, booknu):
        for book in self.booklist:
            if book.booknu == booknu:
                self.booklist.remove(book)

    def updatebook(self, booknu, bookprice):
        for book in self.booklist:
            if book.booknu == booknu:
                book.bookprice = bookprice

    def findbook(self, name):
        resultlist = []
        for book in self.booklist:
            if book.bookname.find(name) >= 0:
                resultlist.append(book)
            else:
                print("Don't find the book.")

    def showbook(self, booknu):
        if self.booklist:
            print("The book list")
            for book in self.booklist:
                print(book.booknu, book.bookname, book.bookprice, book.booksumary)
        else:
            print("There nothing in the library.")


li = library()
while True:
    print("\naddbook(1)")
    print("deletebook(2)")
    print("updatebook(3)")
    print("findbook(4)")
    print("showbook(5)")
    print("outbook(6)")
    action = input("请输入操作编号（1-6）:")
    if action == '1':
        booknu = int(input("输入书号: "))
        bookname = input("输入书名: ")
        bookprice = float(input("输入价格: "))
        booksumary = input("输入摘要: ")
        new_book = Book(booknu, bookname, bookprice, booksumary)
        li.addbook(new_book)

    elif action == '2':
        booknu = input("请输入图书编号：")
        li.deletebook(booknu)
        li.showbook()

    elif action == '3':
        booknu = input("请输入图书编号：")
        bookprice = input("请输入图书价格：")
        li.updatebook(booknu,bookprice)
        li.showbook()

    elif action == '4':
        bookname = input("请输入图书名称：")
        li.findbook(bookname)

    elif action == '5':
        li.showbook()

    elif action == '6':
        break
