运用Python语言编写程序制作英文学习词典,词典有4个基本功能:添加、查询、删除和退出。程序读取源文件路径下的txt格式词典文件,若没有就创建一个。词典文件存储方式为“英文单词 中文单词”,每行仅有一对中英释义。程序会根据用户的选择进入相应的功能模块,并显示相应的操作提示。当添加的单词已存在时,显示“该单词已添加到字典库”;当查询的单词不存在时,显示“字典库中未找到这个单词”;但需要删除某个单词时先查询再删除该单词的全部中英文释义。
一、演示效果
1、整体效果
2、添加:
3、添加相同单词时:
4、查找
5、查找文档中不存在时
5、删除
二、源码
PyCharm + Python3 + PyQt5
1、工程结构
2、PyQt5设计UI源码

4、主程序
import sys from dic_UI import Ui_MainWindow from PyQt5.QtWidgets import * from dictionary import DIC if __name__ == '__main__': app = QApplication(sys.argv) mainWnd = QMainWindow() ui = Ui_MainWindow() # 可以理解成将创建的 ui 绑定到新建的 mainWnd 上 ui.setupUi(mainWnd) display = DIC(ui, mainWnd) mainWnd.show() sys.exit(app.exec_())

稳了!魔兽国服回归的3条重磅消息!官宣时间再确认!
昨天有一位朋友在大神群里分享,自己亚服账号被封号之后居然弹出了国服的封号信息对话框。
这里面让他访问的是一个国服的战网网址,com.cn和后面的zh都非常明白地表明这就是国服战网。
而他在复制这个网址并且进行登录之后,确实是网易的网址,也就是我们熟悉的停服之后国服发布的暴雪游戏产品运营到期开放退款的说明。这是一件比较奇怪的事情,因为以前都没有出现这样的情况,现在突然提示跳转到国服战网的网址,是不是说明了简体中文客户端已经开始进行更新了呢?
