Python argparse error NameError name file is not defined

Question

I am trying to run a speech to text script and here is a part of that code where I am getting error:

import sys
import argparse

parser = argparse.ArgumentParser()
parser.add_argument('-f', dest=file, type=string)
args = parser.parse_args()

print args.file

But I am getting the folllowing error:

NameError: name 'file_name' is not defined

The right datatype for destination in argpasrse module is string. So, you need to pass a string.

parser.add_argument('-f', dest="file", type=string)
