服務端
實作目標
- GUI顯示人機互動聊天內容，當客戶端輸入不完整內容，如’how old’,服務器能回復年齡等，
- GUI當客戶端輸入“send a file”，服務器端回復“please input the file name:”（在客戶端顯示），
- (此處本文章代碼未實作，需要請聯系博主)當客戶端輸入檔案名后，服務器端如果有該檔案，則發送該檔案，否則回復客戶端“This file does not exist”，客戶端列印接收到的檔案內容，
- （選）實作服務器與多客服通信功能，（若需要，請聯系博主）
- 博主郵箱：3303295829@qq.com
聊天功能模糊實作原理
commonprefix()函式
- os.path.commonprefix()是Python中的方法用于獲取路徑串列中最長的公共路徑前綴，博主采用此函式來猜測對方要表達的真正意思，
實作代碼

客服端
- GUI登錄端代碼見Python的GUI程式設計
- 實作代碼如下：
