【莫烦Python】Tkinter 做简单的窗口视窗 Python GUI
tkinter窗口
import tkinter as tk

var=tk.StringVar()#变量用来代替显示的字符串
#修改text=。。为textvariable=var,l代替label
#在window上面的label
l=tk.Label(window,textvariable=var,
#text='MOG!this is TK!',被上一行更换
bg='green',width=15,
height=2,#label的长和高，以字符为单位
font=('Arial',12)#字体类型和大小
l.pack())

else:

height=2,command=hit_me)#按钮，执行功能或者函数方程，此处执行函数hit_me
b.pack()
window.mainloop()#循环,更新相当与一个大的while循环
#画布
