What are some use cases for frozensets in Python?

Frozensets are immutable sets in Python. They can be used in situations where you need a set that shouldn't change, like as keys in dictionaries.

Can you give me an example of using frozensets as dictionary keys?

Sure! You can use a frozenset to represent a unique combination of items, like a set of coordinates, and use it as a key in a dictionary to store values associated with those coordinates.

Are there any performance benefits to using frozensets?

Yes, frozensets can be more memory efficient than regular sets, especially when you have a large number of items that won't change.

What about using frozensets in function arguments?

Frozensets can be used as function arguments when you want to ensure that the input set remains unchanged during the function execution.

Can frozensets be used in set operations?

Absolutely! Frozensets support operations like union, intersection, and difference, just like regular sets.
