How to create namespace packages in Python? -


i have python 3 project following structure:

project/ | +--root/    |    +--__init__.py    |    +--sub/       |       +--__init__.py       |       +--actualcode.py

i want use "namespace packages" lib shares common namespace other related libs in separate projects. import statement should this:

from root.sub.actualcode import

the __init__.py file in root folder contains following statement create namespace package:

from pkgutil import extend_path __path__ = extend_path(__path__, __name__)

but cannot reference code when import root.sub. works when write:

from sub.actualcode import # doesn't work "root.sub..."!

what should use root namespace?

namespace packages can built distribute. trick add following line parameter of setup:

setup(   # ...   namespace_packages  = ["root"] )

the rest of example in question correct.
