5 - Declaration

5.1 - console_scripts

In Python -

setuptools generates scripts for you:

  • with the correct extension (on Windows an .exe file, no need to create an file association)

Distributions can specify console_scripts entry points, each referring to a function which can be used as a command

When a console_scripts aware installer such as pip installs the distribution, it will create a command-line wrapper for each entry point.


6 - Location

6.1 - Path

Path of the script itself

import os 
script_path = os.path.realpath(__file__)
script_dir_path = os.path.dirname(script_path)

6.2 - Installation
