sys.argv

sys.argv is a list in Python's sys module that contains the command-line arguments passed to a Python script. It allows scripts to accept and process input parameters when executed from the terminal or command line. The first element (sys.argv[0]) is the script name, and subsequent elements are the arguments provided.

Also known as: sys.argv, argv, command line arguments, cli args, sys argv

Why learn sys.argv?

Developers should learn sys.argv to create command-line tools, automate tasks with configurable inputs, or build scripts that require runtime parameters. It's essential for writing flexible Python applications that can be integrated into shell scripts, pipelines, or batch processing workflows, such as data processing scripts with file paths or configuration options.
