What are some examples of libraries in Python 3.12?

Python 3.12 includes several new and updated libraries. Some notable examples are 'tomllib' for TOML parsing, 'zoneinfo' for timezone support, and 'asyncio' enhancements.

Can you give me a brief example of how to use 'tomllib'?

Sure! Here's a simple example:

import tomllib

with open('config.toml', 'rb') as f:
    config = tomllib.load(f)
print(config)

This code reads a TOML file and loads it into a Python dictionary.

What about 'zoneinfo'? How can I use it?

You can use 'zoneinfo' to work with time zones like this:

from zoneinfo import ZoneInfo
from datetime import datetime

dt = datetime.now(ZoneInfo('America/New_York'))
print(dt)

This will give you the current time in New York.

Are there any new features in 'asyncio'?

Yes! Python 3.12 introduced new features like 'TaskGroup' for better task management and improved error handling in asynchronous code.
