What are hashable types in Python?
In Python, hashable types are those that have a fixed hash value during their lifetime. This means they can be used as keys in dictionaries.
Can you give me some examples of hashable types?
Sure! Examples of hashable types include integers, floats, strings, and tuples (as long as the tuple contains only hashable types).
Are lists and dictionaries hashable?
No, lists and dictionaries are not hashable because they are mutable, meaning their contents can change.
Why is it important for a type to be hashable?
Hashable types are important because they allow for efficient data retrieval in hash tables, which are used in dictionaries and sets.
