How to use Python -m

The python -m option is used to run a Python module as a script. This is useful when you want to execute a module directly from the command line.

Here’s an example of how to use python -m to run the json.tool module:

python -m json.tool input.json

Here, the json.tool module is being used to pretty-print the contents of the input.json file. The -m option tells Python to run the module as a script.

You can also use python -m to run other modules that you’ve created. For example, if you have a module called my_module.py, you can run it like this:

python -m my_module arg1 arg2

Here, the my_module module is being run with the arguments arg1 and arg2.

Overall, the python -m option is a convenient way to run Python modules as standalone scripts, without having to write a separate script file.
