if isinstance(value, int): uses isinstance(value, int), which correctly checks if value is an int or subclass.Final Answer:
if isinstance(value, int): -> Option CQuick Check:
Use isinstance() for type checks [OK]
Quick Trick: Use isinstance() to check types safely [OK]

- Using 'is' or '==' incorrectly for type comparison
- Not checking type at all
