The Ultimate Guide to Python Programming With Python 3.10 - @wraps Decorator

The video tutorial explains how decorators in Python can affect the metadata of functions, specifically their docstrings. It highlights the issue where the metadata of a function is overwritten by a processor function when decorators are used. To address this, the functools.wraps decorator is introduced, which helps preserve the original function's metadata by copying it to the processor function. The tutorial concludes with a demonstration of using functools.wraps to maintain the function's docstring and name.
