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!")

Would it be good practice to have the catch-all except statement followed by a raise statement to catch all possible exceptions and name them?
