A "flag" is defined globally, and if the "flag" value is False, then it blocks when the program executes the Event.wait method, and if the "flag" value is true, then the Event.wait method is no longer blocked.Clear: Set "Flag" to FalseSet: Sets

Functions and variables of the function在python程序中，函数都会创建一个新的作用域，又称为命名空间，当函数遇到变量时，Python就会到该函数的命名空间来寻找变量，因为Python一切都是对象，而在命名空间中，都是以字典形式存在着，这些变量名，函数名都是索引，而值就是，对应的变量值和函数内存地址。在python中可以用globals()查看全局变量，locals()局部变量。>>> global_v = ‘全局变量‘>>> def func():...
