不过需要注意的是,如果我们使用global关键字来声明变量:# outside function def outer(): message = 'local' # nested function def inner(): # declare global variable global message message = 'nonlocal' print("inner:", message) inner() print("outer:", message) outer() 那么最终的打印输出结果为...

After the function is executed, a new global variable will be added 在某个作用域内任意位置只要有为变量赋值的操作,该变量在这个作用域内就是局部变量,除非使用global进行了声明。 如果局部变量与全局变量具有相同的名字,那么该局部变量会在自己的作用域内隐藏同名的全局变量。 As long as there is an ...
In that case, you can use the global keyword to declare that you want to refer to the global variable.The general syntax to write a global statement is as follows:Python global variable_0, variable_1, ..., variable_n Note that the first variable is required, while the rest of the ...
