+======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>
