Thinking about these things at an earlier stage of the development process will make it easier for you to get your application ready for deployment. env file is that it becomes much easier to develop with environment variables in mind early on.
This file is included with your project locally but not saved to source control so that you aren't putting potentially sensitive information at risk.Įnter fullscreen mode Exit fullscreen modeįor most applications, that's all the information you should need to be productive with python-dotenv however there are a few additional features which you can read about in the python-dotenv documentation. env file is a text file containing key value pairs of all the environment variables required by your application. It will also keep your environment variable names and values isolated to the same project that utilizes them.Ī. env file will enable you to use environment variables for local development without polluting the global environment namespace. Eventually naming conflicts becomes an issue and every new variable requires a lengthy prefix to distinguish itself from similar variables.
The process of setting or changing an environment variable is time consuming and over time the number of environment variables you have to manage grows out of control. At some point during development you will need to think about the environment in which your application will run and the potentially sensitive or environment specific information your application will need to perform its tasks.Įnvironment variables are one of the key ways software developers provide an application with this kind of information, however running and testing an application locally that is dependent on environment variables can be a hassle if you are setting those variables on your local machine's environment.
