Hi, I was asked this by one of my friends too. There are many ways to go about doing this and I can show you how I go about doing it.

Check out the following template. It is basically a simple template which I use:

import sys
import getopt

try:
    opts, args = getopt.getopt(sys.argv[1:], 'm:p:h', ['miner=', 'params=', 'help'])
except getopt.GetoptError:
    usage()
    sys.exit(2)

for opt, arg in opts:
    if opt in ('-h', '--help'):
        usage()
        sys.exit(2)
    elif opt in ('-m', '--miner'):
        miner_name = arg
    elif opt in ('-p', '--params'):
        params = arg
    else:
        usage()
        sys.exit(2)

Also, do note that there is no set limit on the number of parameters that you can put in to the code.

Hope this helped!
