[tmdeveloper007]

Summary of What Needs to be Done

Remove the duplicate from flask import jsonify import from src/routes/main_routes.py. The jsonify function is imported twice on lines 6 and 28, causing redundant import overhead.

• Remove the second from flask import jsonify statement on line 28 of src/routes/main_routes.py

Impact that it Would Provide

• Cleaner, DRY imports in the main routes module
• Reduces unnecessary import resolution overhead
• Follows Python best practices of avoiding duplicate imports
