opts, args = getopt.getopt(sys.argv[1:],"hle:t:p:cu:",
["help","listen","execute","target","port","command","upload"])
while using like above code,is using argv in place of sys.argv[1:] same or when to use it.then hle is written together and others written separately.is there a reason for that or can be written like h:l:e:t:p:c:u.
is argparse,getopt and optparse same.which do you think is better
