How do I use environment variables in my application?
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 in Python?
Sure! You can use the os module. For example, import os; os.environ['MY_VAR'] = 'value' sets an environment variable.
How do I access that variable later in my code?
You can access it using os.environ.get('MY_VAR'), which will return 'value' if it exists.
What if I want to use a .env file?
You can use the python-dotenv package. Just create a .env file with your variables and load it using load_dotenv().
