What is the difference between mutable and immutable memory

You can see, in the list, we can change any value. In a case of the tuple, we can not change the value of the object value after creating the tuple.

Based on the datatype of the variable you are using. Just as, list and dict are always mutable, the tuple and frozenset are always immutable.

Covert the tuple into a list. Add or delete elements from the list Convert list back to a tuple. Save my name, email, and website in this browser for the next time I comment. What do you want to Learn Today? Code Difference Between Python. Why is tuple immutable when the list is mutable?

FWIW, I am not so sure that mutable objects use more memory per se. I also think that is not the main reason they exist. Mutable objects can be modified, immutable objects can't.

NSMutableString objects can be edited and maintain the same pointer. A common practical difference is: If you create 1 NSString and then assign another one to it, then edit either one of them, they will now be pointing to different strings.
