when i execute my program without an argument i receive,
> infile = sys.argv
> IndexError: list index out of range
> is there a way that i could suppress this and add my own error code
The direct way to handle this is to check the length of sys.argv
first. sys.argv is a list, so you can ask the list for its length.
Do you know how to do that?
