This is a simple bash script for unix that will do your job:

per module:

#!/bin/sh
while read p; do
  pip install $p
done < requirements.txt

or you can simple pass:

pip install -r requirements.txt

in requirements.txt , enter the modules name:

django
numpy
lxml
#.... so on

You can then run the bash script ./script.sh

If you want to do the installation of the modules from your python script, you can use setup :

from setuptools import setup

setup(
    # ...
    install_requires=['module']
)
