Apply @syntax to Wrap a Function

Summary

Use @decorator syntax and functools.wraps to wrap functions while preserving metadata.

Problem statement

Create a decorator called make_upper that: - Converts the string returned by the wrapped function to uppercase. - Uses functools.wraps to preserve the wrapped function's __name__ and __doc__. - Raises a TypeError if the wrapped function returns a non-string result. Apply this decorator using the @syntax to the provided example functions. Ensure the decorator works for functions with and without parameters.

Task

Implement a decorator make_upper that converts string results from a wrapped function to uppercase and preserves the function's __name__ and __doc__.

Examples

Input format

A call expression or attribute access on a decorated function, e.g. greet('name') or greet.__name__

Output format

The return value of the decorated function or a preserved attribute like __name__ or __doc__.

Constraints

- Use functools.wraps in the decorator. - The decorator should accept functions that take any arguments. - If the wrapped function returns a non-string, raise TypeError. - Preserve function metadata (__name__, __doc__).
