Python+mysql=接单管理系统

Python+mysql=接单管理系统

起因：接的单子越来越多，各种信息记录太麻烦，容易弄丢还不好统计
经过：闲得慌用python花了两个下午写了个自用的接单管理系统,复习一下pyqt5的使用
结果：就这样吧，懒得办了
思路就是本人太懒，所以直接上代码

    def update(self, id):

    def get_hearders(self):

        cursor = self.db.cursor()

if __name__ == '__main__':
    dh = database_handle()
    print(dh.update(19))
    pass

效果展示

这些是一些图标，背景图。在相对路径images文件夹下

注意事项：因为我用的我电脑上MySQL，所以要使用得配置mysql，然后自己根据数据库操作代码修改配置，虽然简陋，但是满足自己的小需求可还行
