Command Line Arguments
Many programming languages, including Python, support the use of command line arguments. They are also sometimes referred to as switches. A command line argument is essentially a way of configuring and applying settings when a program or script is ran at the command line.
Refer to the first chapter's section Command Line Interface or CLI for more information.
In Python, command line arguments are best implemented through the module argparse available in the standard library. This module helps with:
- Defining Arguments
- Storing Arguments
- Designating default values
- Designating required arguments
- Designing help messages
For examples that utilize command line arguments, check the examples and projects sections.
