so I can not import a module from the parent directory? Or where did I
make an error?
Thanks for help

try
import sys
sys.path.append('C:\\')
from A.B import bmodule
is there any 'automatic' way of finding the top level
directory?basically the 'top level directory is the first directory
going upwards, that doesn't contain a __init__.py file.
what if some user has an __init__.py file the top level directory of
your package ?
of course you could do this 'manually' by
doing:
# assume, that this module is A.amodule
import sys
import os
# I'd love to have a similiar automatic construct
if __name__ == "__main__":
level = 1 # or function locating how far to go up before
# finding a dir, whcih does not contain a __init__.py
mydir = os.path.split(__file__)[0]
topdir = os.path.join( mydir,*(("..",)*level))
abstop = os.path.abspath(topdir)
sys.path.append(abstop)
## now you can import with the normal module paths
import A.blo
print "and I found blo",dir(A.blo)

You don't want to do that and you don't need it neither. That's what the
env variable PYTHONPATH is for. set it correctly, install your package
inside and everything works just fine (+standard). With a linux OS it
easy to create smb links to point to any working directory. It should be
possible on windows as well.
If your package is meant to be destributed, you may use setup.py
