just asking. in C++, why do we need to define signed & unsigned integer? why don't we always use signed? it's better. we can freely assign plus and minus. so what's the catch of using unsigned?

If except can handle common errors very well, doesn't that make the use of raise redundant inside of a try-except block? For example: try: print( 5 / 0 ) except ZeroDivisionError: raise ValueError("An error occurred!") What's the difference if we handle it this way: try: print( 5 / 0 ) except (ZeroDivisionError, ValueError): print("An error occurred!")
