2.8、设置 Button 的边框

# bd(bordwidth)：缺省为 1 或 2 个像素
# 创建 5 个 Button 边框宽度依次为：0，2，4，6，8
from Tkinter import *
root = Tk()
for b in [0,1,2,3,4]:
Button(root,
text = string(b),
bd = b).pack()
root.mainloop()

代码

from tkinter import *
quehui = Tk()
for b in [0,1,2,3,4,5,6,7,8,9]:
Button(quehui,
text = str(b),
bd = b
).pack()
quehui.mainloop()
