Tkinter 简介

图形用户界面 (GUI)是一种用户界面形式，它允许用户使用图标、菜单、窗口等项目通过视觉指示器与计算机进行交互。它比用户与计算机交互的命令行界面 (CLI) 具有优势通过仅使用键盘编写命令并且其使用比 GUI 更困难。

什么是 Tkinter？

Tkinter是用于创建 GUI 应用程序的内置Python模块。它是在Python中创建 GUI 应用程序最常用的模块之一，因为它简单易用。您无需担心单独安装 Tkinter 模块，因为它已经随Python提供。它为 Tk GUI 工具包提供了一个面向对象的接口。其他一些可用于创建我们自己的 GUI 应用程序的Python库是

  • 基维
  • Python Qt
  • wxPython

      在所有 Tkinter 中使用最广泛

root.title("First_Program")
  
# Label is what output will be 
# show on the window
label = Label(root, text ="Hello World !").pack()
