async def process_users(users: List[User]) -> None:
    """Process a list of users asynchronously."""
    tasks = [user.greet() for user in users]
    results = await asyncio.gather(*tasks)

    for result in results:
        print(result)

# Example usage
if __name__ == "__main__":
    users = [
        User("Alice", "alice@example.com", 30),
        User("Bob", "bob@example.com"),
        User("Charlie", "charlie@example.com", 25)

Inline Math

Einstein’s famous equation: \(E = mc^2\) demonstrates mass-energy equivalence.

Block Math

The fundamental theorem of calculus:

\[ \frac{d}{dx}\left( \int_{a}^{x} f(t)\,dt\right) = f(x) \]

Complex equations with matrices:

\[ \begin{bmatrix} a & b \\ c & d \end{bmatrix} \begin{bmatrix} x \\ y \end{bmatrix} = \begin{bmatrix} ax + by \\ cx + dy \end{bmatrix} \]

💬 Blockquote Styling
