| ## Combine the split files into a single file named 'ILtest.db.gz' | |
| ```python | |
| import gzip | |
| import os | |
| import shutil | |
| def combine_files(input_prefix, num_parts, output_file): | |
| with gzip.open(output_file, 'wb') as f_out: | |
| for i in range(1, num_parts + 1): | |
| part_file = f"{input_prefix}_part{i}.gz" | |
| with gzip.open(part_file, 'rb') as f_in: | |
| shutil.copyfileobj(f_in, f_out) | |
| os.remove(part_file) | |
| combine_files('ILtest', 2, 'ILtest.db.gz') | |
| ``` | |
