在公司實(shí)習(xí)。公司推崇Python和Django框架，所以也得跟著學(xué)點(diǎn)。

簡(jiǎn)單瞅了下Tkinter，和Canvas配合在一起，還算是簡(jiǎn)潔的界面開發(fā)API。threading.Thread創(chuàng)建新的線程，其多線程機(jī)制也算是方便。

只是canvas.create_rectangle居然不是繪制矩形，而是新建了矩形控件這點(diǎn)讓人大跌眼鏡。先開始，在線程里每次都重繪多個(gè)矩形（隨數(shù)組變化），其實(shí)是每次都新建了N個(gè)矩形，結(jié)果內(nèi)存暴增。原來(lái)，對(duì)矩形進(jìn)行變更時(shí)，只需用canvas.itemconfig即可。

下面就是截圖（時(shí)間太晚，明日還得上班，做得非常粗糙...沒事時(shí)再慢慢修正）。

而代碼如下：
