can somebody explain difference in these two almost similar codes??

Original code: https://code.sololearn.com/391/#py 1st variation: - why no output. def decor(func): def wrap(): print("============") func() print("============") return wrap def print_text(): print("Hello world!") decor(print_text) 2nd variation: def wrap(func): print("============") func() print("============") return wrap def print_text(): print("Hello world!") s=wrap(print_text) s()

This is an excellent article on decorators that explains the whole concept starting from the basics. https://realpython.com/primer-on-JUMP_LINK__&&__python__&&__JUMP_LINK-decorators Highly recommended. Very long, so take your time with it. But totally worth reading.
