我从“学习”斯堪德·哈维德到我需要评论:
from sys import argv
因此,我做了以下工作:从玩具模块中进口零件。
我知道有什么样的动力,但我却在混淆如何把这一要素称作玩具模块? 变数、方法、功能? 变数?
而且,鉴于该法典,这是否意味着所有玩具模块都进口到我的节目中,或者只加一夫?

我知道有什么动力,但我难以确定如何把这一要素称作玩具模块?
我认为,你指的是<><>>
>>> import sys
>>> callable(sys.argv)
False
现在,正如上文提及的“不可靠”一样,假定该模块尚未装满。 这意味着什么? 当你进口一个单元时,它就添加到一个称作玩具的字典上。 模块。
>>> import sys
>>> print sys.modules.keys

字典扫描仪使该模块无法重载。 进口表检查了玩具.摩杜里,以防止该模块重载。
如果你真的进入了单元,请看一下清单的ys。
如果你改写文字,并想立即改变口译,则将文字重载。
>>> reload(sys)
>>> help(reload)
Help on built-in function reload in module __builtin__:
reload(...)
reload(module) -> module
Reload the module. The module must have been successfully imported before.
因此,你们比以往更加想知道单元和单元属性:D。
