If you created a Python module package directory called "firstPackage" as described in the previous tutorial, you can load it into your Python execution session using the "import" statement:

1. Make sure the module pacakge directory is a sub directory of the current directory:

\fyicenter>dir
 <DIR>          firstPackage

2. Start the Python in interactive mode:

\fyicenter>python
Python 3.6.2 (v3.6.2:5fd33b5, Jul  8 2017, 04:14:34) [MSC v.1900 32 bit (Intel)]
 on win32
Type "help", "copyright", "credits" or "license" for more information.
>>>

3. Load the module package. Note that the Python code in the __init__.py file will be executed once when you load the package directory for the first time. If you load it again, it will not be executed any more.

>>> import firstPackage
Loading first package...
>>> import firstPackage

4. If you want to load module inside a package, you need to load it using the dot (.) expression format:

>>> import firstPackage.secondModule
Loading second module...
