python查看所有内置函数模块类型的方法 怎么查看python所有内置函数,内置函数(BIF,built-infunctions)是python内置对象类型之一,不需要额外导入任何模块即可直接使用,这些内置对象都封装在内置模块_builtins_之中,用C语言实现并且进行了大量优化,具有非常快的运行速度

但如果在模块中定义了名叫__all__的list变量,则只有__all__内指定的属性、方法、类可被导入。 二、运行方式 python模块的两种运行方式是通过__name__变量进行区分的,两种方式分别为:本地脚本运行、其他模块导入运行。如果一个模块直接在本地脚本执行,则__name__的值为“__main__“;否则其值为本模块名称。
sys模块官方解释:This module provides access to some variables used or maintained by the interpreter and to functions that interact strongly with the interpreter. 这个模块可供访问由解释器使用或维护的变量和与解释器进行交互的函数。 sys.argv 命令行参数List,第一个元素是程序本身路径 ...
All functions in the subprocess module are convenience wrappers around the Popen() constructor and its instance methods. Near the end of this tutorial, you’ll dive into the Popen class. Note: If you’re trying to decide whether you need subprocess or not, check out the section on deciding...
