What are the differences between sets and frozensets in Python?
Sets are mutable, meaning you can change them after creation, while frozensets are immutable.
Can you give me an example of when to use a frozenset?
Sure! Use a frozenset when you need a constant collection of items, like keys in a dictionary.
Are there any operations that I can't perform on frozensets?
Yes, you can't add or remove elements from a frozenset since it's immutable.
What about performance? Are frozensets faster than sets?
Frozensets can be faster for membership tests because they are hashable and can be used as dictionary keys.
Can I convert a set to a frozenset?
Absolutely! You can convert a set to a frozenset using the frozenset()
constructor.
