method for arg parsing

[jedelman8]

Yandy,
I started the work to create a method for arg parsing as mentioned earlier. Now you can see what I mean. The method is only used when running it as a program. Feel free to finish it....if not, I'll try to later in the week too... :)

I just finished submitting a pull-request seconds before getting this, looks similar, let me know what you think.

also, the parser is not an iterable item

Sys.argv is, no?

argparse library and sys.argv are way different.

argparse is meant to simplify command-line handling, not positional and can be required or optional.

if we use sys.argv, that's essentially a list of strings, so we're getting into manipulation of strings to find the place where -i is, where -m is and so forth.

something like

if sys.argv[1] == '-i' or sys.argv[1] == --ip_address:
 self.address = sys.argv[2] 
# 2 because 1 would be the position and 2 where the actual value you want would be, 
# but that's hoping.

and you can see the chaining of if statements that would require, even if we put it in a for loop, it's not efficient, how many times do we need to iterate to find the actual values?

hence why I structured it the way I did.

Yup. I knew they were different, just not sure how. Have heard very good things about argpasrse though!

Will take a look later. Thanks.
