To avoid confusion, the directory that is the package should be named
as you want the imports to appear; e.g. if you want to 'import
foo.module_a', then name the directory containing 'module_a.py' as
'foo/'.
This often results in::
foo/
setup.py
foo/
__init__.py
module_a.py
test/
__init__.py
test_module_a.py
That is, the *project* directory (containing all the files) is named
'foo/'; the *package* directory (where all the implementation code is
found) is named 'foo/foo/', and the unit tests are found in the
directory 'foo/test/'.
That's normal, though if it confuses you you might want to rename the
project directory. I'm often doing development on multiple
version-control branches, so each project directory is named for the
branch it contains; within each of those, the same 'foo/' name is used
for the package directory.

You should install the package into a place where Python's import path
will find it. Read up on using the standard library 'distutils'
mechanism for this; it involves writing a 'setup.py' file to define
the parameters for installation of your package.

Yes. The top-level directory is used for containing a number of files,
including 'setup.py', that should not be part of the installed
package.

I hope the above makes it clearer what I prefer for this situation.
