I have a script that takes an which basically takes a command line
argument and prints after processing. If I don't give the argument to
the script, it gives me a ValueError:
ValueError: need more than 1 value to unpack
I was trying to utilizing this space, if there is no argument I want it
to show:
usages: myscriptpy [option] [argument]
options:
--help print this help message and exit
Nothing more than that. I was looking on the argparse module, it can
do the stuffs I want, but
I don't to rewrite and mess up my current script. What should I do?
