内建函数 Build-in Function,启动python解释器,输入dir(__builtins__), 可以看到很多python解释器启动后默认加载的属性和函数,这些函数称之为内建函数, 这些函数因为在编程时使用较多,cpython解释器用c语言实现了这些函数,启动解释器 时默认加载。 这些

Python Built-in function 默认dir()机制对不同类型的对象表现不同,因为它尝试生成最相关但非完整的信息。 如果对象是模块对象,则列表包含模块属性的名称。 如果对象是类型或类对象,则列表包含其属性的名称,并递归地包含其基础的属性。 #没有对象>>>dir()['__annotations__','__builtins__','__doc__','...
