======Python Modules and Packages======
  * A Python module is a file containing Python code.
  * A package is a group of modules in a subdirectory.
    * To make a directory package include a file in the directory named //__init__.py//.

======Example=====
To create a package //foo// that contains a module //bar// and function //hello//.

<code>
from foo.bar import hello

hello()
</code>

Directory named //foo// contains empty file named //__init.py__// and file named //bar.py//. The file contains the function //hello//.

General scheme
<code>
from <package>.<sub package>.<module> import <function/class>
</code>

The //__init__.py// could contain the following import statement.

<code>
from <package>.<module> import <function/class>
</code>

Which would allow the module to be imported into other modules with the following import statement that imports directly from the package and not the module.

<code>
from <package> import <function/class>
</code>
