Pyqt5實現(xiàn)英文學(xué)習(xí)詞典-創(chuàng)新互聯(lián)

運用Python語言編寫程序制作英文學(xué)習(xí)詞典，詞典有4個基本功能：添加、查詢、刪除和退出。程序讀取源文件路徑下的txt格式詞典文件，若沒有就創(chuàng)建一個。詞典文件存儲方式為“英文單詞 中文單詞”，每行僅有一對中英釋義。程序會根據(jù)用戶的選擇進(jìn)入相應(yīng)的功能模塊，并顯示相應(yīng)的操作提示。當(dāng)添加的單詞已存在時，顯示“該單詞已添加到字典庫”；當(dāng)查詢的單詞不存在時，顯示“字典庫中未找到這個單詞”；但需要刪除某個單詞時先查詢再刪除該單詞的全部中英文釋義。

創(chuàng)新互聯(lián)專注為客戶提供全方位的互聯(lián)網(wǎng)綜合服務(wù)，包含不限于做網(wǎng)站、成都網(wǎng)站設(shè)計、西峽網(wǎng)絡(luò)推廣、重慶小程序開發(fā)、西峽網(wǎng)絡(luò)營銷、西峽企業(yè)策劃、西峽品牌公關(guān)、搜索引擎seo、人物專訪、企業(yè)宣傳片、企業(yè)代運營等，從售前售中售后，我們都將竭誠為您服務(wù)，您的肯定，是我們大的嘉獎；創(chuàng)新互聯(lián)為所有大學(xué)生創(chuàng)業(yè)者提供西峽建站搭建服務(wù)，24小時服務(wù)熱線：028-86922220，官方網(wǎng)址：muchs.cn

一、演示效果

1、整體效果

2、添加：

3、添加相同單詞時：

4、查找

5、查找文檔中不存在時

5、刪除

二、源碼

PyCharm + Python3 + PyQt5

1、工程結(jié)構(gòu)

2、PyQt5設(shè)計UI源碼
