How do I serialize sets in Python with standard library only?

In Python, you can serialize sets using the `json` module from the standard library. Sets are not directly serializable to JSON format, but you can convert them to a list or a dictionary first.

Here’s an example of how to serialize a set using the `json` module:


import json

# Example set
my_set = {1, 2, 3}

# Serialize to JSON by converting to a list
serialized_set = json.dumps(list(my_set))

print(serialized_set)  # Output: [1, 2, 3]
