Python Dependency management practices

Now I'm taking part in node.js project and i like "node way" of dependecy management.

I'll provide some examples for those who haven't worked with npm

All deps are stored in package.json file, which is indexed by version control system. When i clone repo, i just type npm install in terminal and it installs everything. As far as i know, pip freeze is able to do it, but:

On production server I can type npm install --production and all my build tools, testing frameworks, etc. are not installed. Just production deps.

So, the question is:

How do you split production and development dependecies with pip(or other tool)?

There is a nice solution, it is quite new tool, called pipenv. Seems an analog of npm for python.

I would create two virtualenvs (venv for Python 3) with a separate requirements.txt file for each, like requirements-production.txt and requirements-develop.txt, but that looks a bit strange to me.

Personally, I usually use git's branches to separate production/development code. Most of the development goes in the develop branch, there's a single requirements.txt (which can change over time, for sure). When everything's alright and/or the development cycle has ended, I just merge it with the master branch. Haven't had a need to test different versions of dependencies simultaneously.
