# Debugging and Improving Python Script for Data Processing

## Current Issues
- The script fails to process large datasets efficiently
- Error message: `MemoryError: Unable to allocate array of size 128 MB`
- Slow performance when handling multiple files

## Suggested Improvements
1. **Memory Management**: Implement chunking for large datasets
   ```python
   def process_in_chunks(file_path, chunk_size=1000):
       with open(file_path, 'r') as file:
           while True:
               chunk = file.readlines(chunk_size)
               if not chunk:
                   break
               process_chunk(chunk)
   ```
2. **Parallel Processing**: Use multiprocessing for concurrent file handling
3. **Error Handling**: Add comprehensive error handling for file operations

## Implementation Plan
1. Refactor the current script to implement chunking
2. Add multiprocessing support for file processing
3. Implement comprehensive error handling
4. Test with various dataset sizes
5. Optimize performance based on test results
