>>> help(conf_intf) Help on function conf_intf in module __main__: conf_intf(intf, ip, mask) 本函数可生产接口配置 >>> 此时,我们就可以用help内置函数来探索一下它了,这与我们help其它模块函数本质上是一样的。在自定义函数中,这种简短注释是被广泛推荐的,例如函数期望多少参数,各为什么类

每个模块module 有自己的命名空间,称global namespace,记录模块的变量,包括functions、classes、导入的modules、module级别的变量和常量。 build-in命名空间,它包含build-in function和exceptions,可被任意模块访问。 某段Python代码访问 变量x 时,Python会所有的命名空间中查找该变量,顺序是: local namespace 即当前函数...
