Emulate pip install -r requirements from shell

Question

Is it possible to achieve the same behaviour of:

pip install -r requirements.txt

But programmatically with python?

For example (pseudocode):

from pip.reqs import install_requirements

install_requirements(file='requirements.txt')

And if not why? What is the best practice?

You need pip to be install prior to

import pip

# to install requirements
pip.main(['install', '-r', 'requirements.txt'])

# to install one package
pip.main(['install', 'package_name'])
