Exceptions and raises
 0 Votos
 1 RespuestaIf 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!")

    positives,negatives=[],[]
    if not isinstance(n,list):
         raise ValueError
        return 
    else:
         for i in n:
         if i>=0:
             positives.append(i)
         if i<0
             negatives.append(i)
