How to iterate over arguments

Question

I have such script:

import argparse

parser = argparse.ArgumentParser(
                description=\'Text file conversion.\'
                )
parser.add_arg         


        

Answer 1

Parsing the _actions from your parser seems like a decent idea. Instead of running parse_args() and then trying to pick stuff out of your Namespace.

import argparse

parser = argparse.ArgumentParser(
                description='Text file conversion.')
parser.add_argument("inputfile", help="file to process", type=str)
parser.add_argument("-o", "--out", default="output.txt",
                help="output name")
parser.add_argument("-t", "--type", default="detailed",
                help="Type of processing")
options = parser._actions
for k in options:
    print(getattr(k, 'dest'), getattr(k, 'default'))  

You can modify the 'dest' part to be 'choices' for example if you need the preset defaults for a parameter in another script (by returning the options in a function for example).
