作用域的搜索顺序是 Local -> Enclosing -> Global -> Built-in Python中用nonlocal关键字声明为Enclosing范围,用global关键字声明为全局范围。 我们来看一个global 和 nonlocal 会如何影响变量绑定的例子: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 def scope_test(): def do_local(): spam = "...

• enclosing function: 外部嵌套函数的名字空间. • globals: 函数定义所在模块的名字空间. • __builtins__: 内置模块的名字空间. 想想看,如果将对象引⼊入 __builtins__ 名字空间,那么就可以在任何模块中直接访问,如同内置函 数那样.不过鉴于 __builtins__ 的特殊性,这似乎不是个好主意. >>> _...

However, sys.breakpointhook() can be set to some other function and breakpoint() will automatically call that, allowing you to drop into the debugger of choice. New in version 3.7. (二).大意 这个函数会使你进入调试模式。具体来说,它调用sys.breakpointhook(),直接传递args和kws。
