wxpython实现简单图书管理系统

用wxpython实现的简单图书管理系统，可以实现增加图书，删除图书，修改图书，查看图书。后台数据库为mysql数据库，采用的pymysql连接数据库。系统界面如下：

代码如下：

1.书本类代码

#author = liuwei  date = 2017-06-02
from datetime import *                                               #导入日期模块
__metaclass__ = type
class Book:'''一个书本信息类，包括书本名字，作者名字和书本简单信息'''def __init__(self, bookName = "", author = "", content = ""):self.bookName = bookName                                      #书本名字self.author = author                                          #作者名字self.content = content                                        #书本信息self.add_date = date.today()                                  #书本添加日期def setBookName(self, name):self.bookName = namedef getBookName(self):return self.bookNamedef setAuthor(self, author):self.author = authordef getAuthor(self):return self.authordef setContent(self, content):self.content = contentdef getContent(self):return self.contentdef getAddDate(self):return self.add_dateif __name__ == "__main__":mybook = Book()print(mybook.date)

2.数据库操作类代码

#author = liuwei date = 2017-06-02
#数据库帮助类
import pymysql
from book import *__metaclass__ = type
class DBHelper:def getCon(self):'''获取操作数据库的curcor即游标，首先的建立连接，需要服务器地址，端口号，用户名，密码和数据库名'''#为了能用中文，得加上编码方式conn = pymysql.connect(host = "localhost", port = 3306, user = "root", password = "201392260", db = "library", charset = "utf8")return conndef insertBook(self, book):'''向数据库中book表插入书本信息，book为Book类对象，包含书本基本信息'''sql = "insert into book(name, author, content, add_date) values(%s, %s, %s, %s)"conn = self.getCon();if conn ==None:returncursor = conn.cursor()cursor.execute(sql, (book.getBookName(), book.getAuthor(), book.getContent(), book.getAddDate()))conn.commit()cursor.close()conn.close()new_id = cursor.lastrowidprint("新插入键值id为:", new_id)return new_iddef getAllBook(self):'''返回数据库中，book表中所有的书本信息'''sql = "select *from book"conn = self.getCon()if conn == None:returncursor = conn.cursor()rownum = cursor.execute(sql)              #执行并返回找到的行数#获取查询结果rows = cursor.fetchall()list = []for item in rows:bitem = (item[0], item[1], str(item[4]))list.append(bitem)conn.commit()cursor.close()conn.close()return listdef getBookById(self, bookid):'''根据书本id值来寻找书本信息'''sql = "select book.name, book.author, book.content from book  where id=%s"conn = self.getCon()if conn == None:returncursor = conn.cursor()cursor.execute(sql, (bookid, ))                     #参数以元组形式给出row = cursor.fetchone()                             #取到第一个结果conn.commit()cursor.close()conn.close()return row                                          #返回该书本信息def saveUpdate(self, bookid, book):'''用book对象来修改id为bookid的书本信息'''sql = "update book set book.name=%s, book.author=%s, book.content=%s where book.id=%s"conn = self.getCon()if conn == None:returncursor = conn.cursor()cursor.execute(sql, (book.getBookName(), book.getAuthor(), book.getContent(), bookid))conn.commit()cursor.close()conn.close()def deleteBook(self, bookid):'''根据书本id来删除书籍'''sql = "delete from book where book.id = %s"conn = self.getCon()if conn == None:returncursor = conn.cursor()cursor.execute(sql, (bookid, ))conn.commit()cursor.close()conn.close()if __name__ == '__main__':db = DBHelper()#book = Book("秦腔", "贾凹平", "讲的是大西北夏家和白家的事情，由引生口述。")#db.insertBook(book)list = db.getAllBook()for item in list:print(item)
