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!")

Hmm. But in the case we delete a row (toghether with the ID) there will be a gap between the sequence of the ID's. Does auto_increment fill that gap when a new user is created, or will it just add 1 to the last id in the table?

Ques: can we write virtual before an overridden function from the base class?? if yes which f1() should it call base class f1() or derived class f1()???
