Create Professional Python Programs Using Argparse
Using python and argparse we can create professional Python programs very quickly with the module argparse doing the heavy lifting. We have all seen the option --help / -h well they are built into argparse and of course we can create our own options. Managing data types is easy as we can set what type of data we can expect
import argparse
parser = argparse.ArgumentParser()
parser.add_argument('val', help='A value to convert expressed an integer', type=int)
parser.add_argument('-v', '--verbose', help='Print more detail', action='store_true')
contype = parser.add_mutually_exclusive_group(required=True)
contype.add_argument('-f', '--fahr', help='Enable to covert from F to C', action='store_true')
contype.add_argument('-c', '--cent', help='Enable to covert from C to F', action='store_true')
args = parser.parse_args()
if args.verbose and args.fahr:
print("This is the result")
c = (args.val - 32)/1.8
print(f"{args.val}f is {c:.2f}c")
exit(0)
if args.fahr:
c = (args.val - 32)/1.8
print(f"{args.val}f is {c:.2f}c")
exit(0)
if args.verbose and args.cent:
print("This is the result")
f = (args.val * 9 / 5) + 32
print(f"{args.val}c is {f:.2f}f")
exit(0)
if args.cent:
f = (args.val * 9 / 5) + 32
print(f"{args.val}c is {f:.2f}f")
exit(0)
