This is because directories have no inherent meaning to python.  A
module is normally a file.  If you want to group a bunch of files
together you have to use a package. See the docs on how to make a
package.  But the namespace structure within a package isn't based on
the directory tree either.  It's usually set up by __init__.py within
the package which imports modules defined in the package into the
namespace.

Hope this helps.
