Program Code – When Python 3.13: Upcoming Features in Python 3.13

import sys
import asyncio

# Check for minimum required Python version
assert sys.version_info >= (3, 13), 'This program requires Python 3.13 or later.'

# Upcoming feature: Structural Pattern Matching (PEP 634)
# Example: Simplified HTTP response handling using pattern matching
def handle_http_response(status_code):
    match status_code:
        case 200:
            return 'Success'
        case 404:
            return 'Not Found'
        case 500:
            return 'Internal Server Error'
        case _:
            return 'Unknown Status'

# Upcoming feature: Improved Generics (PEP 646)
# Example: Type checking for generic containers
from typing import TypeVar, Generic

T = TypeVar('T')

class Box(Generic[T]):
    def __init__(self, item: T):
        self.item = item

    def get_item(self) -> T:
        return self.item

# Use the new feature in asyncio to run a coroutine
async def fetch_data():
    # Simulate fetching data from a database or API
    await asyncio.sleep(1)
    return {'data': 'sample data'}

def main():
    # Example usage of Structural Pattern Matching
    print(f'HTTP Response Handler Test: {handle_http_response(404)}')

    # Example usage of Improved Generics
    int_box = Box[int](123)
    print(f'Generic Box Test: {int_box.get_item()}')

    # Example usage of new asyncio feature
    loop = asyncio.get_event_loop()
    data = loop.run_until_complete(fetch_data())
    print(f'AsyncIO Coroutine Test: {data}')

if __name__ == '__main__':
    main()

Code Output:

HTTP Response Handler Test: Not Found
Generic Box Test: 123
AsyncIO Coroutine Test: {'data': 'sample data'}

Code Explanation:

The code begins by ensuring it will only run on the required Python version, asserting that Python 3.13 or later is being used, which is critical for accessing the upcoming features.

The handle_http_response function showcases the Structural Pattern Matching feature from PEP 634. This function takes a status code as an input and returns a corresponding message. The match and case syntax provides a cleaner, more readable alternative to multiple if-elif-else blocks.

Next, we have an example of the Improved Generics as proposed in PEP 646. We define a TypeVar T and a generic class Box that can contain any type specified by T. Upon instantiation with Box[int](123), we create a box that specifically contains an integer, and the get_item method is type-checked to return an integer as well.

In the fetch_data coroutine, we simulate an asynchronous operation like fetching data from an external service, using asyncio.sleep to represent the delay. This also demonstrates the newly improved features in the asyncio module.

Finally, the main function ties it all together, showcasing how each of these features might be used in practice. The pattern matching is tested by passing in a 404 HTTP status code; the generics by creating a Box with an integer; and the async feature by running the coroutine to fetch data.

The architecture of the code is simple: function definitions followed by their usage in the driver code, the main function. This design separates the demonstration of each PEP proposal for clarity. The use of an if __name__ == '__main__': block ensures that main only runs when the script is executed directly, not when imported as a module.

Overall, this script is a primer for the hypothetical features which might come in Python 3.13, presented in a way that demonstrates their potential real-world applications in a program.
