[Tutor] Run application from MS-DOS with sys.argv

[Susana Iraiis Delgado Rodriguez]

Hello!

I'm going to answer to the question I posted in this list.
After a search trouhg web and analize the code, I just had to add a
try/except statement. Now I get what I need. Here is the information:

directorio = sys.argv[1]
extension = sys.argv[2]
csv_salida = sys.argv[3]
#Here I add the line:
try:
     if len(sys.argv) == 4:
     ........................
     ........................
else:
        print "Tus argumentos no son correctos"
and here:
except IndexError:
    print "Tus argumentos no son correctos"
