📘 Difference Between is and == in Python

In Python, both is and == are comparison operators, but they serve different purposes.

🔹 Main Difference

🔹 Example

a = [1, 2, 3]
b = [1, 2, 3]
c = a

print(a == b)  # True  → values are equal
print(a is b)  # False → different objects in memory
print(a is c)  # True  → same object in memory

🔹 Output

True
False
True

🔹 Rule of Thumb

• Use == → When you want to check if two objects have the same value.
• Use is → When you want to check if two variables refer to the same object in memory.

✅ Summary:

• == → Compares values.
• is → Compares identity (memory location).
