What are some examples of using frozensets in Python?

Frozensets are immutable sets in Python. They can be used in various scenarios. Would you like to see some code examples?

Yes, please provide a few code examples.

Sure! Here's a simple example:

# Creating a frozenset
my_frozenset = frozenset([1, 2, 3, 4])
print(my_frozenset)

This will output: frozenset({1, 2, 3, 4}). You can also use frozensets as keys in dictionaries.

Can you show me how to use frozensets as dictionary keys?

Absolutely! Here's an example:

# Using frozenset as a dictionary key
my_dict = {frozenset([1, 2]): 'a', frozenset([3, 4]): 'b'}
print(my_dict[frozenset([1, 2])])  # Output: 'a'
