Composer analogue for python?

Question

Python

Hello.
I could not find it, but is it possible to set the list of required packages for any installer in the repository with the python application (like composer.json in php)?
I suspect that pip has such an option, but I didn't find it.
ps using python3

Answer 1

The simplest is to store the list in the requirements.txt file (the name can be anything, but it's accepted):

Flask==0.10.1
Flask-Admin>=1.0.0

Versions can be specified in a variety of ways, including specific commits/branches/tags from version control systems.
Install dependencies:
in the folder with this file
Another option is to describe the dependencies in setup.py, but this is more needed for libraries.
