New submission from Tom Browder <tom.brow...@gmail.com>:
When I use the argparse module, and I enter my program name with NO arguments
or options, I would like the argparser to output something like:
Usage: <program name> [options]
Use option '-h' for help.
I haven't yet found how to do that in the argparse module source code, but I do
that now in my programs by adding this code near the beginning of the program:
# give rudimentary help if nothing but prog name is entered
import os
# get program name as it is called
pnam = os.path.basename(sys.argv[0])
Use = "Usage: {0} [options]".format(pnam)
if len(sys.argv) == 1:
print(Use)
print("Use option '-h' for help.")
sys.exit()
