Pull Request Overview

This PR restructures the Primary and Secondary language test to separate them into distinct test phases. The code now:

1. Tests secondary languages first, then disables ports before moving to primary language testing
2. Adds a sleep delay between secondary and primary language test phases
3. Removes a trailing blank line at the end of the test function

Line 122 uses tab characters for indentation instead of spaces. Python PEP 8 requires spaces for indentation. Replace the tab with appropriate spaces to maintain consistent indentation.

Suggested change

	time.sleep(3)
	# (blank line preserved, now with spaces)
