Meaning of python -m flag
From Python Docs:
Since the argument is a module name, you must not give a file extension (.py). The
module-nameshould be a valid Python module name, but the implementation may not always enforce this (e.g. it may allow you to use a name that includes a hyphen).Package names are also permitted. When a package name is supplied instead of a normal module, the interpreter will execute
<pkg>.__main__as the main module. This behaviour is deliberately similar to the handling of directories and zipfiles that are passed to the interpreter as the script argument.
If you type python --help
You get
// More flags above-m mod : run library module as a script (terminates option list)// and more flags belowA great many things in a terminal will show you how to use it if you either use command --help or man command
The -m stands for module-name.
From Command line and environment:
python [-bBdEhiIOqsSuvVWx?] [-c command | -m module-name | script | - ] [args]
