This is for Python 3.
Here is a basic Python program that demonstrates the idea
#!/usr/bin/env python3
import argparse
helpDesc = "Compiles code into bytecode. V0.2"
argParser = argparse.ArgumentParser(description = helpDesc )
argParser.add_argument("inputfile", help="Specify input file(s).")
argParser.add_argument("--verbose", "-v", help="Enable verbose output.", action="store_true" )
argParser.add_argument("--output", "-o", help="Output filename.", default="OUT")
args = argParser.parse_args()
verbose = args.verbose
inputfile = args.inputfile
if (verbose): print ("Input file:", inputfile)
All you have to do is import the argparse module, add the arguments, parse them and then treat the whole thing as a giant dictionary of data. It’s incredibly simple and handles everything.
For more information, The Python Docs contains a lot of detail. Mostly though, the code above is all you need.
