 * Use shared code whenever possible - don't reinvent the wheel. Ansible offers the ``AnsibleModule`` common Python code, plus :ref:`utilities <appendix_module_utilities>` for many common use cases and patterns.
 * Import ``ansible.module_utils`` code in the same place as you import other libraries.
