Using sys.argv in examples

This example demonstrates the use of sys.argv in example .py files.

By default, all example .py files will be run by Sphinx-Gallery without any arguments. Notice below that sys.argv is a list consisting of only the file name. Further, any arguments added will take on the default value.

This behavior can be changed by using the reset_argv option in the sphinx configuration, see Passing command line arguments to example scripts.

Out:

sys.argv: ['/home/circleci/project/examples/plot_7_sys_argv.py']
parsed args: Namespace(option='default')

import argparse
import sys

parser = argparse.ArgumentParser(description='Toy parser')
parser.add_argument('--option', default='default',
                    help='a dummy optional argument')
print('sys.argv:', sys.argv)
print('parsed args:', parser.parse_args())

Total running time of the script: ( 0 minutes 0.313 seconds)

Estimated memory usage: 8 MB
