Added Comments for Code Sections

[staiton]

In this commit, I added comments to explain each section of the code. Here's a breakdown of the comments:

1. Python Version Check:

   • Added a comment to explain that we're checking if the current Python version meets the minimum requirement of 3.0.

2. Load Environment Variables:

   • Commented to clarify that we're loading environment variables, possibly containing sensitive information like API keys, from a .env file.

3. Retrieve API Key:

   • Added a comment to indicate that we're retrieving the API key from the environment variables and exiting if it's missing.

4. Main Script Execution:

   • Provided a comment to highlight that this is the entry point of the script.

5. Get Current Date:

   • Explained that we're obtaining the current date and time.

6. Format Date as String:

   • Commented to indicate that we're formatting the date as a string in a specific format ("%c").

7. Initialize NasaAPI Instance:

   • Added a comment to show that we're creating an instance of the custom NasaAPI class, which likely handles interactions with NASA's API.

8. Fetch Today's Image:

   • Explained that we're calling the 'get_today_image' method, possibly sending a request to NASA's API to retrieve today's image.

These comments provide detailed explanations for each section of the code, making it easier for developers to understand and maintain the codebase.
