根据你提供的代码,我发现在执行创建数据表的语句时出现了问题。你在创建表时表名前添加了 use 关键字,这是不正确的,因为 use 是MySQL的关键字,不能作为表名使用。正确的做法应该是将 use 放在CREATE TABLE后面的括号中,作为表的名称。例如,你的创建表的语句应该是这样的: ``` sql = f'create table `use` ({list} varchar(800))' ``` 另外,你在插入数据时也需要注意语法错误,插入数据时需要使用 INSERT INTO 语句,而不是 INSERT IGNORE INTO 语句。正确的插入数据的语句应该是这样的: ``` sql = f'insert into `use` (`{list}`) values (%s)' ``` 带有参数的语句中表名和字段名需要用反引号 `` 包围起来,而不是用括号 () 包围。

import pymysql class MysqlDBUtil(): # 字典输出 def __init__(self, host, user, password, database, charset): # host = "localhost" # 指定访问的服务器,本地服务器指定“localhost”,远程服务器指定服务器ip地址 # port = 3306 # 指定端口号,范围在0-65535 # user = "root" # 用户名 # password = "123456" # 密码 # database = "sys" # 数据库的名字 # charset = "utf8" # 数据库的编码方式 # 建立连接 self.connect = pymysql.Connect(host=host, port=3306, user=user, passwd=password, db=database, charset=charset) # 数据库的查询 def query(self , sql): cursor = None res = None try: cursor = self.connect.cursor() cursor.execute(sql) res = cursor.fetchall() except Exception as e: print(str(e)) finally: cursor.close() return res # 数据库的增删改 def uid(self , sql): cursor = None try: cursor = self.connect.cursor() cursor.execute(sql) self.connect.commit() except Exception as e: print(str(e)) self.connect.rollback() finally: cursor.close() #数据库的关闭 def sql_close(self): self.connect.close() import pytest import allure import logging from utils.mysql_database_connection_utils import MysqlDBUtil import utils.mysql_database_connection_utils class TestChaxun(): def mysql_connect(self): self.conn = MysqlDBUtil("localhost", "root", "123456", "sys", "utf8") def teardown_class(self): self.conn.sql_close() def test1(self): data = self.conn.query("SELECT * from stu WHERE name = '张三' ") print(data)

这段代码中的问题可能是在TestChaxun类中的mysql_connect方法中,没有使用self关键字来定义conn属性。应该将mysql_connect方法中的 "self.conn" 更改为 "self.db",因为在类的初始化方法中已经定义了 "self.connect"。修改后的代码如下: ``` class TestChaxun(): def mysql_connect(self): self.db = MysqlDBUtil("localhost", "root", "123456", "sys", "utf8") def teardown_class(self): self.db.sql_close() def test1(self): data = self.db.query("SELECT * from stu WHERE name = '张三' ") print(data) ``` 另外,你需要确保在运行测试之前已经安装了pytest和allure模块,并且将utils.mysql_database_connection_utils模块添加到PYTHONPATH中,以便测试代码能够正确地导入MysqlDBUtil类。

请你逐行解释一下以下代码class StudentView: def __init__(self, parent_window, student_id): parent_window.destroy() # 销毁主界面 self.window = tk.Tk() # 初始框的声明 self.window.title('学生信息查看') self.window.geometry('300x450') # 这里的乘是小x label = tk.Label(self.window, text='学生信息查看', bg='pink', font=('Verdana', 20), width=30, height=2) label.pack(pady=20) self.id = '学号:' + '' self.name = '姓名:' + '' self.gender = '性别:' + '' self.age = '年龄:' + '' # 打开数据库连接 db = pymysql.connect(host="localhost", port=3306, user="root", password="123456", database="student", charset="utf8") # db = pymysql.connect("localhost", "root", "123456", "student") # 打开数据库连接 cursor = db.cursor() # 使用cursor()方法获取操作游标 sql = "SELECT * FROM student_k WHERE id = '%s'" % (student_id) # SQL 查询语句 try: # 执行SQL语句 cursor.execute(sql) # 获取所有记录列表 results = cursor.fetchall() for row in results: self.id = '学号:' + row[0] self.name = '姓名:' + row[1] self.gender = '性别:' + row[2] self.age = '年龄:' + row[3] except: print("Error: unable to fetch data") db.close() # 关闭数据库连接 Label(self.window, text=self.id, font=('Verdana', 18)).pack(pady=5) Label(self.window, text=self.name, font=('Verdana', 18)).pack(pady=5) Label(self.window, text=self.gender, font=('Verdana', 18)).pack(pady=5) Label(self.window, text=self.age, font=('Verdana', 18)).pack(pady=5) Button(self.window, text="返回首页", width=8, font=tkFont.Font(size=16), command=self.back).pack(pady=25) self.window.protocol("WM_DELETE_WINDOW", self.back) # 捕捉右上角关闭点击 self.window.mainloop() # 进入消息循环 def back(self): StartPage(self.window) # 显示主窗口 销毁本窗口

这段代码定义了一个名为 StudentView 的类,该类用于展示学生信息界面。在该类的初始化方法 __init__ 中,首先销毁了父窗口,然后创建了一个名为 window 的 Tkinter 窗口。接着设置了窗口的标题和大小,并创建了一个 Label 用于显示标题。之后定义了四个变量 id、name、gender、age,并打开了一个 MySQL 数据库的连接。接着使用 cursor() 方法获取操作游标,并定义了一个 SQL 查询语句。然后执行 SQL 语句,获取查询结果,并将查询结果赋值给 id、name、gender、age 四个变量。最后创建了四个 Label 用于显示学生信息,并创建了一个“返回首页”的 Button,设置了该 Button 的字体大小和点击事件。最后设置了窗口右上角关闭按钮的点击事件,并进入了 Tkinter 的消息循环。back 方法用于返回到主窗口并销毁当前窗口。

局域网五子棋游戏:娱乐与聊天的完美结合

标题“网络五子棋”和描述“适合于局域网之间娱乐和聊天!”以及标签“五子棋 网络”所涉及的知识点主要围绕着五子棋游戏的网络版本及其在局域网中的应用。以下是详细的知识点: 1. 五子棋游戏概述: 五子棋是一种两人对弈的纯策略型棋类游戏,又称为连珠、五子连线等。游戏的目标是在一个15x15的棋盘上,通过先后放置黑白棋子,使得任意一方先形成连续五个同色棋子的一方获胜。五子棋的规则简单,但策略丰富,适合各年龄段的玩家。 2. 网络五子棋的意义: 网络五子棋是指可以在互联网或局域网中连接进行对弈的五子棋游戏版本。通过网络版本,玩家不必在同一地点即可进行游戏,突破了空间限制,满足了现代人们快节奏生活的需求,同时也为玩家们提供了与不同对手切磋交流的机会。 3. 局域网通信原理: 局域网(Local Area Network,LAN)是一种覆盖较小范围如家庭、学校、实验室或单一建筑内的计算机网络。它通过有线或无线的方式连接网络内的设备,允许用户共享资源如打印机和文件,以及进行游戏和通信。局域网内的计算机之间可以通过网络协议进行通信。 4. 网络五子棋的工作方式: 在局域网中玩五子棋,通常需要一个客户端程序(如五子棋.exe)和一个服务器程序。客户端负责显示游戏界面、接受用户输入、发送落子请求给服务器,而服务器负责维护游戏状态、处理玩家的游戏逻辑和落子请求。当一方玩家落子时,客户端将该信息发送到服务器,服务器确认无误后将更新后的棋盘状态传回给所有客户端,更新显示。 5. 五子棋.exe程序: 五子棋.exe是一个可执行程序,它使得用户可以在个人计算机上安装并运行五子棋游戏。该程序可能包含了游戏的图形界面、人工智能算法(如果支持单机对战AI的话)、网络通信模块以及游戏规则的实现。 6. put.wav文件: put.wav是一个声音文件,很可能用于在游戏进行时提供声音反馈,比如落子声。在网络环境中,声音文件可能被用于提升玩家的游戏体验,尤其是在局域网多人游戏场景中。当玩家落子时,系统会播放.wav文件中的声音,为游戏增添互动性和趣味性。 7. 网络五子棋的技术要求: 为了确保多人在线游戏的顺利进行,网络五子棋需要具备一些基本的技术要求,包括但不限于稳定的网络连接、高效的数据传输协议(如TCP/IP)、以及安全的数据加密措施(如果需要的话)。此外,还需要有一个良好的用户界面设计来提供直观和舒适的用户体验。 8. 社交与娱乐: 网络五子棋除了是一个娱乐游戏外,它还具有社交功能。玩家可以通过游戏内的聊天系统进行交流,分享经验和策略,甚至通过网络寻找新的朋友。这使得网络五子棋不仅是一个个人娱乐工具,同时也是一种社交活动。 总结来说,网络五子棋结合了五子棋游戏的传统魅力和现代网络技术,使得不同地区的玩家能够在局域网内进行娱乐和聊天,既丰富了人们的娱乐生活,又加强了人际交流。而实现这一切的基础在于客户端程序的设计、服务器端的稳定运行、局域网的高效通信,以及音效文件增强的游戏体验。

足底支撑相到达73%是什么问题

<think>好的,我现在要处理用户的问题:“足底支撑相达到73%可能的原因及影响”。首先,需要理解用户提到的“足底支撑相73%”具体指什么。足底支撑相通常指步态周期中脚与地面接触的时间占比,正常范围大约在60%-62%左右。如果达到73%,明显超出正常范围,可能意味着步态异常。 接下来,需要确定可能的原因。可能的原因包括生物力学异常,比如足弓异常(扁平足或高弓足)、踝关节活动度受限,或者肌肉力量不足,特别是小腿和足部肌肉。另外,神经系统疾病如脑卒中或帕金森病可能影响步态控制。骨骼关节问题如关节炎、髋膝关节病变也可能导致支撑时间延长。还有代偿性步态,比如因疼痛或受伤而改变步态模式。 然后是

Java Web应用开发教程:Struts与Hibernate实例解析

在深入探讨所给文件的标题、描述以及标签后,我们可以从中学到关于Struts和Hibernate的知识,以及它们如何在构建基于MVC模式的高效Java Web应用中发挥作用。 **标题解读** 标题中提到了“Struts与Hibernate实用教程”以及“构建基于MVC模式的高效Java Web应用例子代码(8)”,这意味着本教程提供了在开发过程中具体实施MVC架构模式的示例和指导。在这里,MVC(Model-View-Controller)模式作为一种架构模式,被广泛应用于Web应用程序的设计中,其核心思想是将应用分为三个核心组件:模型(Model)、视图(View)和控制器(Controller)。模型负责数据的处理和业务逻辑,视图负责展示数据,而控制器负责处理用户输入以及调用模型和视图去完成业务流程。 **描述解读** 描述部分进一步强调了该教程包含的是具体的例子代码,这些例子是实现高效Java Web应用的一部分,并且教程分成了10个部分。这表明学习者可以通过实际的例子来学习如何使用Struts和Hibernate实现一个基于MVC模式的Web应用。Struts是Apache Software Foundation的一个开源Web应用框架,它采用MVC模式来分离业务逻辑、数据模型和用户界面。Hibernate是一个开源的对象关系映射(ORM)工具,它简化了Java应用与关系数据库之间的交互。 **标签解读** 标签“j2ee,源码”揭示了本教程的适用范围和技术栈。J2EE(Java Platform, Enterprise Edition)是一个用于开发企业级应用的平台,它提供了构建多层企业应用的能力。源码(Source Code)表示本教程将提供代码级别的学习材料,允许学习者查看和修改实际代码来加深理解。 **压缩包子文件的文件名称列表解读** 文件名称列表中的“ch8”表示这一部分教程包含的是第八章节的内容。虽然我们没有更多的章节信息,但可以推断出这是一个系列教程,而每一个章节都可能涵盖了一个具体的例子或者是MVC模式实现中的一个特定部分。 **详细知识点** 在深入探讨了上述概念后,我们可以总结出以下知识点: 1. **MVC模式**: 详细解释MVC模式的设计原理以及在Web应用中的作用,包括如何将应用程序分为模型、视图和控制器三个部分,以及它们之间的交互。 2. **Struts框架**: 介绍Struts框架的基本组件,如Action、ActionForm、ActionServlet等,以及如何在Web应用中使用Struts框架来实现控制器部分的功能。 3. **Hibernate ORM**: 讲解Hibernate如何通过注解或XML配置文件将Java对象映射到数据库表,以及如何使用Hibernate的会话(Session)来管理数据库交互。 4. **Java Web应用开发**: 讲述开发Java Web应用所需要了解的技术,例如Java Servlet、JSP(Java Server Pages)、JavaBeans等。 5. **实际例子**: 分析提供的例子代码,理解如何将Struts和Hibernate集成在真实的Web应用项目中,完成从数据模型到用户界面的全部流程。 6. **代码实践**: 详细解释例子中提供的源代码,理解其背后的逻辑,并能够通过实践加深对代码结构和功能的理解。 7. **企业级应用开发**: 阐述J2EE平台的重要性和它在构建大型、可扩展企业级应用中的优势,以及如何利用J2EE平台上的各种技术。 综上所述,这份教程通过结合Struts和Hibernate框架,并运用MVC设计模式,为Java Web应用开发者提供了一个高效的学习路径。通过例子代码的实践,开发者能够更好地理解如何构建和维护复杂的Web应用。
