I see
RELEASE_LEVELS = [ALPHA, BETA, RELEASE_CANDIDATE, FINAL] = ['alpha', 'beta', 'candidate', 'final']
in odoo/conf/release.py of odoo project. I am assuming it's python array. but can't find any detail of it.
What does the two equals mean?
This is a short way to write
ALPHA, BETA, RELEASE_CANDIDATE, FINAL = 'alpha', 'beta', 'candidate', 'final'
RELEASE_LEVELS = [ALPHA, BETA, RELEASE_CANDIDATE, FINAL]
So first it sets the four variables to the corresponding strings, then it sets RELEASE_LEVELS
to a list (not array) of those four strings.
