Installing modules in Python 3

Suppose I have a directory with custom .py files. The directory is called useful_scripts and a subdirectory called tested_scripts which also contains scripts (.py files).

I've seen on some articles, import statements like: 

from useful_scripts.tested_scripts import sth

How could we install our custom directory modules in such a convienient way so that we could access it like above?

If you have multiple modules (Python file with .py ) in directory and want to import one module in another module then first define that directory to a python directory or package

Packages are namespaces which contain multiple packages and modules.Each package in Python is a directory which MUST contain a special file called __init__.py

Python Package

Your directory structure should be like this if you want to import modules or package

enter image description here

Now you can import module a.py in module b.py or module b.py in module a.py

If you want to install custom lib then create setup.py the file where coustomlib directory exists ( create setup.py outside the coustomlib directory or along coustomlib )

in setup.py

#!/usr/bin/env python

from distutils.core import setup
from setuptools import setup, find_packages

setup(name='coustomlib',
  version='1.0',
  description='Python coustom lib ',
  author='your name',
  author_email='[email protected]',
  packages=find_packages(),
 )

for install run 

python setup.py install

After install coustomlib you can import it any module 

import coustomlib

Or

from coustomlib.module1 import a

More info about setup.py
