python relative import weirdness

I have a file:

STARTDIR/module/submodule/config.py

I have another file:

STARDIR/utils/filesys/getAbsPath.py

Why does this line work, in config.py?

from ..utils.filesys import getAbsPath

It seems like .. refers to module, not STARTDIR. There is no utils in module at all. In fact, doing

from .. import 开发者_运维知识库utils

yields

ImportError: cannot import name utils

This should work:

from ...utils.filesystem import getAbsPath

This is because:

• from . import … imports from STARTDIR/module/submodule/
• from .. import … imports from STARTDIR/module/
• from ... import … imports from STARTDIR/
