managing api keys securely is crucial for maintaining the integrity of your applications and protecting sensitive information. here's a comprehensive guide on how to properly load and manage api keys in python.

best practices for managing api keys

1. **avoid hardcoding**: never hardcode api keys directly into your source code. this can lead to accidental exposure, especially if your code is pushed to version control systems (like github).

2. **use environment variables**: store api keys as environment variables. this keeps them separate from your code and allows you to manage them easily across different environments (development, testing, production).

3. **use a configuration file**: for local development, you can use a configuration file that is not tracked by version control (like `.env` files).

4. **use secret management tools**: for production applications, consider using secret management services (like aws secrets manager, azure key vault, or hashicorp vault) to manage and retrieve your api keys securely.

5. **limit permissions**: when generating api keys, ensure they have the minimum permissions necessary for your application to function.

example: loading api keys using environment variables

#### step 1: set up environment variables

on your local machine, you can set environment variables in your terminal. for example, on macos or linux, you can use:

on windows, you can use:

#### step 2: install `python-dotenv` (optional)

if you want to load environment variables from a `.env` file (for local development), install the `python-dotenv` package:

#### step 3: create a `.env` file

create a file named `.env` in your project directory and add your api key:

make sure to add `.env` to your `.gitignore` file so it does not get committed to version control.

#### step 4: load the api key in your python code

here’s a simple example of how to load and use the api key in your python application:
