[Tutor] Fw: Command line args

[ALAN GAULD]

Please use REPLY ALL to include the rest of the group.

The code looks OK although the error that you raise should probably 
be a RuntimeError rather than a SyntaxError since its not really a 
syntax problem.

You can get a list of the built in exceptions by doing:

>>> import exceptions
>>> dir(exceptions)

HTH,

This is how I actually did it after reading a number of your posts:

numLst = []   #an empty list

if len(sys.argv) == 2: #only one filename, please
    infile = open(sys.argv[1], 'r')
elif len(sys.argv) < 2:  #handles the case where no file is provided on
command line
    infilename = raw_input("Name of file: ")
elif len(sys.argv) > 2:  #raises error if more than one filename is provided
    raise SyntaxError, "Too many arguments"
data = open(infilename, 'r')

for x  in data:
    numLst.append(x.strip('\n').split(" "))

Thank you so much for the discussion.  It has been very helpful!
