How to iterate over arguments

Question

I have such script:

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")  args = parser.parse_args()  for arg in args:     print(arg) 

But it doesnt work. I get error:

TypeError: 'Namespace' object is not iterable 

How to iterate over arguments and their value?

Answer 1

Namespace objects aren't iterable, the standard docs suggest doing the following if you want a dictionary:

>>> vars(args) {'foo': 'BAR'} 

So

for key,value in vars(args).iteritems():     # do stuff 

To be honest I'm not sure why you want to iterate over the arguments. That somewhat defeats the purpose of having an argument parser.

Answer 2

Please add 'vars' if you wanna iterate over namespace object:

 for arg in vars(args):      print arg, getattr(args, arg)
