Understanding the difference between == and is in Python is one of the most common Python interview questions.
Many beginners think both are the same, but they serve different purposes.
β == checks value equality
β is checks object identity (memory location)
Example:
If two variables contain the same value, == returns True because the values match.
But is returns True only when both variables point to the same object in memory.
This concept becomes very important when working with:
β’ None
β’ Mutable objects
β’ Large data structures
β Best Practice:
Always use is when comparing with None, because you are checking the object's identity, not just its value.
It may look like a small concept, but it can have a big impact in Python interviews and real-world coding.
