我使用此代码使用Tkinter和python 3.5制作滚动文本窗口，我很好奇我可以做些什么来改变滚动文本的字体大小和颜色 .

import tkinter as tk

 root = tk.Tk()
 deli = 100           # milliseconds of delay per character
 svar = tk.StringVar()
 labl = tk.Label(root, textvariable=svar, height=5)

 def shif():
     shif.msg = shif.msg[1:] + shif.msg[0]
     svar.set(shif.msg)
     root.after(deli, shif)

shif.msg = 'Text example: Blah, Blah Blah'
shif()
labl.pack()
root.mainloop()
python-3.x tkinter
