python-lenv 0.4.0

Quickly and efficiently load environment variables into a class

python-lenv

Welcome to the lenv package page! This package allows you to quickly, efficiently and conveniently load environment variables into a class!

Features

• Loading environment variables into class variables by variable name
• Configuring the loading of changes using a variable of class meta

Installation

You can use your favorite package manager to install/update the lenv package. For example, pip, as in this example:

python3 -m pip install -U python-lenv

Usage/Examples

dotenv

First of all, let's define our .env file, which will be located in the startup directory of the main file.

I put the TOKEN and API_KEY there, in the future we will be able to get them through class variables

TOKEN=FOlCLYqcM.ZRgpwq.IrUyWYwjwSvFmCITCbmOBqvbqpZLWNrufvQKsrawplHMAwICSjBJvSlkJFaeENCrYkdOUeqSwmwQoMbTEJLLFLIGDLXaWF.HsNqciQnXitjhzXO
API_KEY=a3edffac-f4cc-4e68-9fd3-11e942fc7ea6

python

Finally, we come to our first example. We can use class variables to get environment variables directly through the class.

import lenv


class Config(lenv.EnvironmentLoader):
    # This configuration is not important, the default is used `lenv.DefaultMetadata` 
    # which has a file path like .env in it. But for example, let's leave it
    meta = lenv.ConfigurableMetadata(dotenv_path=".env")
    
    # These class variables will be used directly to access environment variables －O－
    TOKEN: str
    API_KEY: str


assert Config.TOKEN == 'FOlCLYqcM.ZRgpwq.IrUyWYwjwSvFmCITCbmOBqvbqpZLWNrufvQKsrawplHMAwICSjBJvSlkJFaeENCrYkdOUeqSwmwQoMbTEJLLFLIGDLXaWF.HsNqciQnXitjhzXO'
assert Config.API_KEY == 'a3edffac-f4cc-4e68-9fd3-11e942fc7ea6'
