compare with is

“Is” checks object’s home Values differ, identity Use with care in Python

python shell for compare with is

In Python, “is” compares identity
Not just values, but where objects reside
Use it carefully, for immutable types
And know when to use “==” for the same plight

I learned about using the “is” keyword in Python to compare object identity. This means that “is” checks if two variables point to the same object in memory, rather than just having the same value. It’s important to note that “is” should not be used to compare values of immutable types like strings and numbers, as they may be cached and re-used by Python. Instead, “==” should be used to compare the values of these types. Additionally, when comparing mutable objects like lists or dictionaries, “is” can be used to check if they are the same object in memory, but “==” should be used if you want to check if they have the same values. Overall, “is” is useful for comparing object identity in Python, but it’s important to use it carefully and understand its limitations.
