An example of an AI chatbot conversation about using environment variables in applications.
How do I use environment variables in my application?
You can use environment variables to store configuration settings outside your code. This helps keep sensitive data secure.
Can you give me an example of setting an environment variable?
Sure! In a Unix-based system, you can set an environment variable like this: export MY_VAR='value'. Then, you can access it in your application.
How do I access these variables in Python?
In Python, you can use the os module. For example, import os; my_var = os.getenv('MY_VAR') will retrieve the value.
What if I want to use a .env file?
You can use the python-dotenv package to load variables from a .env file. Just create a .env file and call load_dotenv() in your code.
