這篇文章主要介紹了python實現的簡單窗口倒計時界面,實例分析了Python基於Tkinter操作windows窗口界面的相關技巧,非常具有實用價值,需要的朋友可以參考下
本文實例講述了python實現的簡單窗口倒計時界面。分享給大家供大家參考。具體分析如下：
下面的代碼通過Tkinter制作windows窗口界面，然後時間了一個簡單的倒計時功能，代碼可以直接運行

Tkinter.Entry(get_window, width=30, textvariable=source).pack() Tkinter.Button(get_window, text="Change", command=lambda: update_specs()).pack() root = Tk() root.title("Countdown") lbl1 = Label() lbl1.pack(fill=BOTH, expand=1) app = App(root) root.mainloop()希望本文所述對大家的Python程序設計有所幫助。
