Automatic version number both in setup.py (setuptools) AND source code?

Question

SITUATION:

I have a python library, which is controlled by git, and bundled with distutils/setuptools. And I want to automatically generate version

Answer 1

Eric's idea was the simple way to go, just in case this is useful here is the code I used (Flask's team did it this way):

import re
import ast

_version_re = re.compile(r'__version__\s+=\s+(.*)')

with open('app_name/__init__.py', 'rb') as f:
    version = str(ast.literal_eval(_version_re.search(
        f.read().decode('utf-8')).group(1)))

setup(
    name='app-name',
    version=version,
 .....
)
