Create a Python Package

In this section you will create a Python package that will become your DNA Center SDK.

Python Packages

Packages are namespaces which contain multiple packages and modules themselves. They are simply directories, but with a twist.

Each package in Python is a directory which MUST contain a special file called __init__.py. This file can be empty, and it indicates that the directory it contains is a Python package, so it can be imported the same way a module can be imported.

Steps

The first task is to create the package that will contain our Python modules.

Note

__init__.py is technically not required as of Python 3.3

STEP 1. CREATE a folder named dnac in the root of the project (cloned) directory

mkdir dnac

STEP 2. CREATE a file named init.py in the dnac folder

touch dnac/__init__.py

STEP 3. MODIFY the file permissions to add execute

chmod +x dnac/__init__.py

Can you import this package?

If you completed these steps you can now import your package in the python interpreter.

That's exciting! You just created your first Python package. Although it doesn't have any functional purpose yet, you learned some of the foundational mechanics required to start the process.
