1. Global scope¶ Any variable defined outside a non-nested function is called a global. As the name suggests, global variables can be accessed anywhere. Example:¶ side=5# defined in global scopedefarea():returnside*sidedefcircumference():return4*sideprint(f"Area of square is{area()}...
这样输出的结果为12,因为func函数调用时定义的X也被认为只属于局部作用域了,但是此时函数g()里定义的x并非全局变量,用前述的global关键字肯定是不行的, 所以又有了nonlocal,这样写: def g(): x = 12 func(): nonlocal x x = 1 func() print(x) g() 这时,输出的结果就是我们预期的1了,nonlocal就...
global用于在局部作用于修改或重定义全局变量 nonlocal用于在内部作用域修改或重定义外部变量(全局变量除外) 这只是很浅的理解方式 注意python的特性,变量有mutable和immutable之分,对于mutable变量的,在内部作用域内做修改时完全可以的,不需要上面两个关键字的修饰,比如下面的程序: a = 12 li = [1, 2, 3] def...
function_a中的变量local_a和module level的变量global_a就在不同的命名空间中,所以print(local_a)会报错。 要想使得local_a可以在函数外部被访问到,只需要加一行代码: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 global_a="I am in global scope"deffunction_a():global local_a ...

For example, if you reference a given name, then Python will look that name up sequentially in the local, enclosing, global, and built-in scope. If the name exists, then you'll get the first occurrence of it. Otherwise, you'll get an error....
