syntax error with KeyError in python 3.2
Question: I'm a beginner using python 3.2 and i have a book whos code is all in python
2.6. i wrote part of a program and keep getting: Syntax Error: invalid syntax
Then python's IDLE highlights the comma after KeyError in my code:

    
    
    from tank import Tank
    
    tanks = { "a":Tank("Alice"), "b":Tank("Bob"), "c":Tank("Carol")}
    alive_tanks = len(tanks)
    
    while alive_tanks > 1:
        print
        for tank_name in sorted( tanks.keys() ):
            print (tank_name, tanks[tank_name])
    
        first = raw_input("Who fires? ").lower()
        second = raw_input("Who at? ").lower()
    
        try:
            first_tank = tanks[first]
            second_tank = tanks[second]
        except KeyError, name:
            print ("No such tank exists!", name)
            continue
    


Answer: Instead of

    
    
    except KeyError, name:
    

try

    
    
    except KeyError as name:
    

Its a difference between Python 2.x and Python 3.x. The first form is no
longer supported.
