Question

I got some confusion in the python add_option

I write the code like this

parser.add_option("-u", "--uniqueness",
              action="store_true", dest="uniqueness", default=False)

Later in the shell, I want to write something like:

if(the user input -u option):
     do something

My question is, how can I write “the user input -u option” in python? I tried to use “if(parser.uniqueness)” however, this command doesn’t work. Btw I am using python 2.7.3 (just wonder if this command will be different from the command in python 3) thx

Firstly, optparse is deprecated, so you should use argparse – but the logic will be similar.

You need to do args = parser.parse_args() somewhere first, and then check in this object with :

if args.uniqueness:
  # potato
