5. The control focus problem, the actual effect is to press the enter key to automatically execute the focus control, bind method

print("button3 clicked")

7. There are three ways to specify the width and height of the button
1. Set the width and height properties in the button
2. Use attributes to specify
Third, use the configure method to specify
b1 = Button(root,text="but1",width=30,height=2)
b1.pack()
b2 = Button(root,text="but2")
b2['width'] = 30
b2['height'] = 2
b2.pack()
b3 = Button(root,text="but3")
b3.configure(width=30,height=2)
b3.pack()

8. anchor refers to the position of the control where the text of the button is located, nsew
for a in ['n', 's', 'e', 'w', 'ne', 'nw', 'se', 'sw']:
Button(root,
text = "anchor",
anchor = a,
width = 30,
height = 3).pack()
The above is simplified code √

9. Change the foreground and background colors
bfg = Button(root,text="change boreground",fg = "red")
bfg.pack()
bbg = Button(root,text="change background",bg = "blue")
bbg.pack ()
'''
'''
10. bd=bordwidth refers to the width of the border, the default value is 1 or 2 pixels
