wxpython实现图书管理系统

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 = 2017-06-02from datetime import *      #导入日期模块__metaclass__ = typeclass 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 = name def getBookName(self): return self.bookName def setAuthor(self, author): self.author = author def getAuthor(self): return self.author def setContent(self, content): self.content = content def getContent(self): return self.content def 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 pymysqlfrom book import *__metaclass__ = typeclass 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 conn def 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:  return cursor = conn.cursor() cursor.execute(sql, (book.getBookName(), book.getAuthor(), book.getContent(), book.getAddDate())) conn.commit() cursor.close() conn.close() new_id = cursor.lastrowid print("新插入键值id为:", new_id) return new_id def 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:  return cursor = 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 list def 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:  return cursor = 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:  return cursor = 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:  return cursor = 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)
