Separate a Python source into separate directories?

Question

Here are a few different Python packages that my company foo.com uses:

com.foo.bar.web
com.foo.bar.lib
com.foo.zig.web
com.foo.zig.lib
com.foo.zig.lib.lib1
com.foo.zig.lib.lib2

Here's the traditional way to store the source on disk:

pysrc/
  com/
    foo/
      bar/
        web/
        lib/
      zig/
        web/
        lib/
          lib1/
          lib2/

PYTHONPATH=pysrc

But for organizational purposes (different teams, different version control, etc.) we want to save them as follows:

bar/
  pysrc/
    com/
      foo/
        bar/
          web/
          lib/
zig/
  pysrc/
    com/
      foo/
        zig/
          web/
          lib/
            lib1/
            lib2/

PYTHONPATH=bar/pysrc:zig/pysrc

Question:

Are there any problems with this second method of organization?

For example, if we are import com.foo, where will Python be looking __init__.py?

Will simling these directories make sense? eg:.

pysrc/
  com/
    foo/
      bar/ -> symlink to /bar/pysrc/com/foo/
      zig/ -> symlink to /zig/pysrc/com/foo/

Any suggestions from the organizing committee are welcome.

Answer 1

Python sys.path ( PYTHONPATH, ), com.foo . , , , , Perl Java, . , __path__, , " " - , Python .

com.foo.bar / com.foo.zig zig/, .

Answer 2

PEP 420, , __init__.py :

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

, (* - __init__.py ):

python com/:

barPath=/myroot/bar/pysrc/
zigPath=/myroot/zig/pysrc/
export PYTHONPATH=$PYTHONPATH:$barPath:$zigPath

( 2.7.14 3.6.4):

from com.foo.bar.web.barweb import BarWeb
from com.foo.zig.web.zigweb import ZigWeb
b = BarWeb()
z = ZigWeb()

__init__.py :

ImportError: No module named zig.web.zigweb
