How do I validate lists in Python in an async application?

In Python, validating lists in an async application can be done using various techniques. One approach is to use asynchronous functions to check the contents and structure of the lists while ensuring that the rest of your application remains responsive.

        import asyncio

        async def validate_list(data):
            if not isinstance(data, list):
                raise ValueError("Input must be a list.")
            for item in data:
                if not isinstance(item, int):  # Example validation: check if all items are integers
                    raise ValueError("List items must be integers.")
            return True

        async def main():
            try:
                result = await validate_list([1, 2, 3, '4'])
                print("List is valid:", result)
            except ValueError as e:
                print("Validation error:", e)

        asyncio.run(main())
