Help in Python decorator

What do "functools.wrap" in Line 2 ? can explaine it 🙏 def decorator(func): @functools.wraps(func) def wrapper_decorator(*args, **kwargs): # Do something before value = func(*args, **kwargs) # Do something after return value return wrapper_decorator

It keeps the specific attributes of func that will normally be shadowed by the wrapper. Eg the name of func

That's partially possible, but how about help string, signature,... you can do it for each one .... or functools.wrap

So what's the advantage of this? just keep the name? Why don't we do this => "wrapper_decorator.__name__ = func.__name__ " instead import functools?
