Python's many command-line utilities

Python’s many command-line utilities

These are Python’s most helpful general-purpose command-line tools.

Command	Purpose	More
`python -m http.server`	Start a simple web server	Video
`python -m webbrowser`	Launch your web browser	Docs
`python -m json.tool`	Nicely format JSON data	Docs
`python -m calendar`	Show a command-line calendar	Docs

`http.server`

Running the http.server module as a script will start a web server on port 8000 that hosts files from the current directory. I use this all the time to preview Sphinx documentation sites (especially when using Sphinx’s dirhtml option which is all about subdirectories of index.html files).
