Implement Python Handler for Step Extraction and Storage

[ckak912]

CodeBuddy will need to extract each step from the API response and store them sequentially in a JSON object for further processing. This issue aims to implement a Python handler to handle this step extraction and storage process.

Steps to implement

1. Create a Python handler to make an API call to the pre-trained model.
2. Implement regex to extract each step from the API response.
3. Store the extracted steps sequentially in a JSON object.
4. Update the database by storing the JSON object in the exercise_details[steps] field.

Acceptance Criteria

• The Python handler successfully retrieves the API response.
• The regex extraction accurately extracts each step from the API response.
• The extracted steps are stored sequentially in a JSON object.
• The JSON object is correctly stored in the exercise_details[steps] field in the database.
• The python handler is designed in a resuable manner to cater to both the "Step-by-Step Process" and "Code Reviewer" functionality.
• The python handler is adaptable to handle the integration of hint and feedback functionality within the "Code Reviewer" feature
