[TriPython] Problems with import after attempting to create pip installable package

[Steve Gambino]

Hello friends,

I'm attempting to learn how to create a pip installable package. So far the
attempt has been relatively successful but for one nagging issue. I'm
hoping if I describe the issue here clearly enough that someone can offer
pointers to help me get to a resolution.

I've created the package (named get_random) successfully with setuptools
and have been able to do a pip install of it in a virtualenv.

The package "get_random" contains a trivial program also named
"get_random". The program, "get_random", imports one module, 'random', and
it has the functions, main(), get_random() and print_random(). After the
pip install of the get_random package, I can call the get_random program
from the command line in the virtualenv and get the expected results. In
otherwords, if I run the following in a terminal I get a resulting random
number, like so:

sgambino-m1:~/vnv_for_pip > get_random
0.0259274305036

However, if I try to import the get_random package into a python REPL I do
not see
a complete list of what is in the package. I only see the following:

>>> dir(get_random)
>>> ['__builtins__', '__doc__', '__file__', '__name__', '__package__',
'__path__']

but I was expecting to see:

>>> dir(get_random)
['__builtins__', '__doc__', '__file__', '__name__', '__package__',
'get_random', 'main', 'print_random', 'random']

If I try to import the get_random package into a script and run the script,
I get the following error:

ncralsgambino-m1:~/vnv_for_pip > ./try_get_random.py
Traceback (most recent call last):
  File "./try_get_random.py", line 5, in <module>
    get_random.print_random()
AttributeError: 'module' object has no attribute 'print_random'

Here is some more detail from the REPL that may give a clue.  I'm wondering
if there is something in the setup.py that I haven't
defined correctly or not defined at all. I could share that if someone
thinks it is worth a look. The setup.py that I started with
was the one that is provided from https://github.com/pypa/sampleproject

Python 2.7.10 (default, Oct 23 2015, 19:19:21)

>>> import get_random
>>> dir(get_random)
['__builtins__', '__doc__', '__file__', '__name__', '__package__',
'__path__']
>>> print(get_random.__file__)
/Users/sgambino/vnv_for_pip/lib/python2.7/site-packages/get_random/__init__.pyc
>>> print(get_random.__package__)
None
>>> print(get_random.__path__)
['/Users/sgambino/vnv_for_pip/lib/python2.7/site-packages/get_random']

If you have bothered to read this far, I hope this has made some sense and
I thank you for any ideas you may be willing to share!
