I have written a python script which uses argeparse module for handling arguments. e.g.
Test_Dual.py -g Linux
Now, I want to give it two options for same argument, like
Test_Dual.py -g Linux -g ESX -g Windows
How can I do that?

Python supports multiple way to parse command line arguments. Which module or library you are using?Mikko Ohtamaa– Mikko Ohtamaa2015-02-05 06:16:08 +00:00Commented Feb 5, 2015 at 6:16

You can do as follows:
import argparse
parser = argparse.ArgumentParser(description=("Program desciption"))
parser.add_argument("-g", "--full-name-of-g", action='append',
help="what is g option for")
args = vars(parser.parse_args())
print(args['full_name_of_g'])
Prints:
['Linux', 'ESX', 'Windows']
Comments
You want the 'append' action to add_argument. This will accumulate values into a list -- once for each time the command line argument is present. e.g.
parser = argparse.ArgumentParser() # yadda yadda
parser.add_argument('-g', action='append')
fake_args_for_demo = '-g Linux -g ESX -g Windows'.split()
namespace = parser.parse_args(fake_args_for_demo)
print(namespace.g) # ['Linux', 'ESX', 'Windows']
