在路径中使用带有两个以上点的模块是否可以?就像在这个例子中:
# Project structure:
# sound
# __init__.py
# codecs
# __init__.py
# echo
# __init__.py
# nix
# __init__.py
# way1.py
# way2.py
# way2.py source code
from .way1 import echo_way1
from ...codecs import cool_codec
# Do something with echo_way1 and cool_codec.
UPD:更改了示例.我知道,这将在实践中发挥作用.但这是一种常见的导入方法吗?
解决方法:
从PEP8开始:
Absolute imports are recommended, as they are usually more readable and tend to be better behaved (or at least give better error messages) if the import system is incorrectly configured (such as when a directory inside a package ends up on sys.path ):
import mypkg.sibling
from mypkg import sibling
from mypkg.sibling import example
However, explicit relative imports are an acceptable alternative to absolute imports, especially when dealing with complex package layouts where using absolute imports would be unnecessarily verbose:
from . import sibling
from .sibling import example
Standard library code should avoid complex package layouts and always use absolute imports.
