'''
The binding methods are usually as follows:
First, use the command attribute declaration when the button component is declared. The command attribute accepts a function name. Note that the function name should not be enclosed by double quotation marks.
Second, use the bind method, which is a method of the MISC class,

# First event binding method
# Do not add any punctuation marks after the command attribute

# The first parameter of BIND is the event type, which is described as follows: <modifier-type-Detail>, here
# Modifier is the modifier. Its values are as follows: control, mod2, M2, shift, mod3, M3, lock, mod4, M4, button1, B1, mod5, M5 button2, b2, Meta, M, button3, B3, ALT, button4, B4, double, button5, B5 triple, mod1, M1. The third type indicates the type, and its values are as follows: Activate, enter, MAP, buttonpress, button, expose, motion,
# Buttonrelease, focusin, mousewheel, circulate, focusout, property, colormap, gravity reparent, configure, keypress, key, unmap, deactivate, keyrelease visibility, destroy, and leave. The third parameter table shows the details, which is an auxiliary description of the second parameter.
# The first parameter may be too complex for the person who just used it. The common left-click button is as follows: <button-1>,
# That is, what I used in the above Code
# The second parameter can be a function name. Remember not to add any punctuation marks. Otherwise, an error will be reported during running.
# When using the BIND function, the second parameter is a function name, which must accept a parameter, that is, the event
