I’ve been looking around for a package manager that can be used with python. I want to list project dependencies in a file.
For example ruby uses Gemfile where you can use bundle install.
How can I achieve this in Python?

Answer
The pip
tool is becoming the standard in equivalent of Ruby’s gems.
Like distribute
, pip
uses the PyPI package repository (by default) for resolving and downloading dependencies.
pip
can install dependencies from a file listing project dependencies (called requirements.txt
by convention):
pip install -r requirements.txt
You can “freeze” the current packages on the Python path using pip as well:
pip freeze > requirements.txt
When used in combination with the virtualenv
package, you can reliably create project Python environments with a project’s required dependencies.
