最近學習了python的jieba分詞庫和wordcloud詞雲庫，誕生了想寫個小demo，使用python實現文章的詞雲圖的繪製，然後需要具有互動介面，並且能夠在沒有python環境的電腦下執行，方便不懂程式設計的人直接使用。

全部程式碼實現的打包exe檔案：WordCloudTool免安裝版

主要使用的庫和軟體如下：

python3.7.1  實現演算法程式語言 jieba 詞語分割 wordcloud 繪製雲圖 matplotlib.pyplot 顯示/儲存雲圖 注意，預設上述環境和庫以安裝完畢！  

介面結構設計

登入介面如下：

註冊頁面如下：

檔案選擇頁面如下：

完整程式碼如下：
