Don't use environment variables, it is generally a bad idea. Use a separate configuration file. You can work out which file to read by using the name of the process group. Examples of config files: https://www.devdungeon.com/content/python-configuration-files <https://www.devdungeon.com/content/python-configuration-files> Or even just use a Python module with the configuration in it and have different sections again keyed off the process group. If you really want to use SetEnv, see: https://modwsgi.readthedocs.io/en/develop/user-guides/configuration-guidelines.html#application-configuration <https://modwsgi.readthedocs.io/en/develop/user-guides/configuration-guidelines.html#application-configuration> but these are only available in context of a request, and are not process wide. Adding them to os.environ on each request is a bad idea and can fail in certain ways. > Also, whatever SetEnv directive I use in .wsgi file, how do I extract the > same in my Python code > > On Friday, 15 November 2019 12:09:33 UTC+5:30, Vaibhav Bajpai wrote: > Iam working on running a Python Flask app with Apache HTTP Server (v2.4) > where Iam attempting to setup an environment variable to identify deploy > environment type (Dev, Prod) and unable to extract the environment variable > via "os.environ" in python code > > After following few posts, i made the following changes I made in key files > of my code.
