[英]Avoiding huge files when following python google-style-guide
Google style guide requires to import modules.谷歌风格指南需要导入模块。 Say I have a non trivial class and several non-trivial derived classes.
假设我有一个非平凡的类和几个非平凡的派生类。 It seems that I have to put them all in the one file otherwise will have to use different prefixes when using them.
似乎我必须将它们全部放在一个文件中,否则在使用它们时将不得不使用不同的前缀。
Personally I prefer one class per file.我个人更喜欢每个文件一个类。 Is there a common idiom to avoid unnecessary large files?
是否有一个常见的习惯用法来避免不必要的大文件?
Eg can I rename several imports into one as long as there is no name conflicts?例如,只要没有名称冲突,我可以将多个导入重命名为一个吗?
import data_main as data
import data_derived_a as data
import data_derived_b as data
With modules, no, there's really no way of doing this that I know of.使用模块,不,我所知道的真的没有办法做到这一点。 If you're happy to put your class in separate files within a package, though, you can import the individual classes in
__init__.py
, and your client modules can import them all at once, like so.但是,如果您愿意将您的类放在一个包中的单独文件中,您可以在
__init__.py
导入各个类,并且您的客户端模块可以像这样一次性导入它们。
# mypackage/a.py
class A:
pass
# mypackage/b.py
class B:
pass
# mypackage/__init__.py
from .a import A
from .b import B
# mymodule.py
from mypackage import A, B
a = A()
b = B()
# Or mymodule.py
import mypackage as p
a = p.A()
b = p.B()
