我有一些问题涉及<条码>进口。 声明:
<编码>进口与带;module>和 from <module> import *?
我怎么能进口一个不是同一目录的单元? (而不是<代码>) 页: 1
请审议: 我是一座新面包车。
<代码>import将模块输入全球名称空间。 <编码>从进口进口这些物品进入名称空间。
因此,附有一个明晰的<代码> 进口。 你们总是必须参考该模块:
>>> import datetime
>>> day = datetime.date.today()
但随附进口上的<代码>,可直接参考这些物项:
>>> from datetime import date
>>> day = date.today()
如果您使用<代码>,从某些模块进口到,将把该模块的所有物品输入贵方的国名空间。 虽然这似乎方便,但最好不要这样做。 它owned倒了,因为在阅读该守则时,很难告诉该单元的哪些内容,而且你使用的名称和你无意中从该模块进口的名字之间可能发生碰撞。
