Package Your Python Code as a CLI
summary
Shows exactly how to turn a Python script into a CLI: copy code, pick arguments, read from stdin/stdout, add a shebang, chmod +x and put the file on PATH, then optionally replace sys.argv with argparse or Typer. Demonstrates a greet_simple example, explains piping and streams, and uses sys.argv → argparse → Typer for progressively richer interfaces. Covers making standalone tools with PEP 723 + UV for self-contained scripts and highlights autogenerated help, virtualenv-per-script behavior, and practical interface design.
