code-foundations

After reviewing the provided code snippet, here are my observations and recommendations:

1. **Function Length**: The `process_data` function is 120 lines long, which violates the Single Responsibility Principle. Break it down into smaller functions, each handling a specific task. This will improve readability and maintainability.

2. **Parameter List**: The `generate_report` function has 7 parameters. Consider using a configuration object or a builder pattern to reduce the number of parameters and make the function call more readable.

3. **Error Handling**: The code lacks proper error handling. Implement try-catch blocks to handle potential exceptions and provide meaningful error messages.

4. **Code Duplication**: There are several instances of duplicated code in the `validate_data` function. Extract the common logic into a separate function to adhere to the DRY (Don't Repeat Yourself) principle.

5. **Naming Conventions**: Some variable names are not descriptive enough. For example, `data` could be more specific, like `user_data` or `transaction_data`. Descriptive names improve code readability and understanding.
