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.

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 0.201 seconds)

Estimated memory usage: 176 MB
