However, handling scenarios where paths might not exist or permissions might restrict access adds complexity. 2. **File Filtering**: The code filters out files ending with `.csv`. Ensuring this filter works correctly even when filenames contain special characters or when there are no `.csv` files requires careful consideration. 3. **Path Construction**: Constructing full paths using `os.path.join()` ensures cross-platform compatibility but requires attention to detail when dealing with different operating systems. 4. **Handling Large Directories**: If directories contain a large number of files or subdirectories, performance considerations come into play. 5. **Edge Cases**: Handling edge cases such as empty directories or directories containing only non-CSV files needs careful handling. ### Extension 1. **Recursive Search**: Extend functionality to search recursively through subdirectories. 2. **Filter Extensions Dynamically**: Allow dynamic specification of file extensions instead of hardcoding `.csv`. 3. **Error Handling**: Implement robust error handling mechanisms for cases like permission errors or invalid paths. 4. **File Modification Time**: Add functionality to filter files based on modification time (e.g., only return `.csv` files modified within the last week). 5. **Parallel Processing**: For very large directories, implement parallel processing techniques to improve performance. 6. **Metadata Collection**: Collect metadata (e.g., file size) along with paths. ## Exercise ### Problem Statement: You are required to enhance the provided function `[SNIPPET]` so that it meets additional requirements: 1. Modify `get_simu_path` function so that it can search recursively through subdirectories. 2. Allow users to specify multiple file extensions dynamically via an argument list (e.g., `['csv', 'txt']`). Ensure backward compatibility where if no extensions are specified, it defaults to just `.csv`. 3. Implement error handling mechanisms: - Raise appropriate exceptions if the provided path does not exist. - Handle permission errors gracefully by logging them without terminating execution. 4. Add functionality to filter files based on their modification time: - Introduce an optional parameter `modified_within_days` which takes an integer value representing days. - Only include files modified within this period. 5. Collect additional metadata (file size) along with each file path returned. ### Constraints: - Use Python standard libraries only. - Ensure your solution is efficient even for large directories. - Maintain cross-platform compatibility. ### Example Usage: python # Example call: paths = get_simu_path('/some/directory', extensions=['csv', 'txt'], modified_within_days=7) # Expected output: # [ # ('/some/directory/file1.csv', {'size': '12345'}), # ('/some/directory/subdir/file2.txt', {'size': '67890'}), # ... # ] ## Solution python import os import time def get_simu_path(path, extensions=None, modified_within_days=None): if not os.path.exists(path): raise FileNotFoundError(f"The path {path} does not exist.") if extensions is None: extensions = ['csv'] current_time = time.time() simu_paths = [] def recursive_search(directory): try: for entry in os.scandir(directory): if entry.is_file(): ext = entry.name.split('.')[-1] if ext.lower() in [ext.lower() for ext in extensions]: mod_time = entry.stat().st_mtime # Check modification time conditionally if modified_within_days is None or (current_time - mod_time <= modified_within_days *86400): size_info = {"size": str(entry.stat().st_size)} simu_paths.append((entry.path, size_info)) elif entry.is_dir(): recursive_search(entry.path) except PermissionError as e: print(f"Permission denied while accessing {directory}: {e}") recursive_search(path) return simu_paths # Example usage: paths = get_simu_path('/some/directory', extensions=['csv', 'txt'], modified_within_days=7) print(paths) ## Follow-up exercise ### Problem Statement: Extend your solution further by adding these functionalities: 1. Implement parallel processing using Python’s `concurrent.futures` module when searching through large directories. 2. Introduce logging instead of printing error messages directly (use Python’s `logging` module). 3. Allow filtering based on additional criteria such as minimum file size (`min_size`) specified in bytes. ### Example Usage: python # Example call: paths = get_simu_path('/some/directory', extensions=['csv', 'txt'], modified_within_days=7, min_size=1024) # Expected output should now consider minimum file size condition too. ## Solution python import os import time import logging from concurrent.futures import ThreadPoolExecutor logging.basicConfig(level=logging.INFO) def get_simu_path(path, extensions=None, modified_within_days=None, min_size=None): if not os.path.exists(path): raise FileNotFoundError(f"The path {path} does not exist.") if extensions is None: extensions = ['csv'] current_time = time.time() simu_paths = [] def process_entry(entry): try: ext = entry.name.split('.')[-1] if ext.lower() in [ext.lower() for ext in extensions]: mod_time = entry.stat().st_mtime # Check modification time conditionally valid_mod_time = modified_within_days is None or (current_time - mod_time <= modified_within_days *86400) # Check minimum size conditionally valid_size = min_size is None or entry.stat().st_size >= min_size if valid_mod_time and valid_size: size_info = {"size": str(entry.stat().st_size)} simu_paths.append((entry.path, size_info)) except PermissionError as e: logging.error(f"Permission denied while accessing {entry.path}: {e}") def recursive_search(directory): try: entries_to_process = [] with ThreadPoolExecutor() as executor: futures = [] entries_to_process.extend(os.scandir(directory)) while entries_to_process: entry_list_batch = entries_to_process[:100] # Process batch-wise futures.extend(executor.submit(process_entry, entry) for entry in entry_list_batch) del entries_to_process[:100] # Remove processed batch new_entries_to_process_batched_from_dirs=[] # Process remaining directory batches concurrently dir_futures=[executor.submit(os.scandir,directory_entry.path) for directory_entry in entry_list_batch if directory_entry.is_dir()] new_entries_to_process_batched_from_dirs.extend([dir_future.result() for dir_future in dir_futures]) entries_to_process.extend([sub_entry for nested_entries_in_dir_batched in new_entries_to_process_batched_from_dirs for sub_entry in nested_entries_in_dir_batched]) # Wait until all futures are done concurrent.futures.wait(futures) except Exception as e: logging.error(f"An error occurred while scanning directory {directory}: {e}") recursive_search(path) return simu_paths # Example usage: paths=get_simu_path('/some/directory', extensions=['csv','txt'], modified_within_days=7, min_size=1024) print(paths) *** Excerpt *** *** Revision 0 *** ## Plan To create an exercise that challenges advanced understanding and requires profound knowledge beyond what's presented directly within an excerpt implies several steps: 1. Integrate complex themes requiring background knowledge across various domains—science, history, philosophy—to ensure comprehension isn't straightforward without prior learning. 2.Utilize sophisticated language structures such as nested counterfactuals ("If X had happened instead of Y...then Z would be true") and conditionals ("If A occurs then B follows unless C intervenes"), demanding higher cognitive engagement from readers to follow logical sequences accurately. 3.Incorporate ambiguity where plausible interpretations require weighing evidence against theoretical knowledge—forcing learners not only to understand what is explicitly stated but also what could be implied under certain conditions. To accomplish this transformation effectively: - The rewritten excerpt will contain references requiring knowledge outside common education—perhaps quantum physics principles explained metaphorically relating back to historical events or philosophical dilemmas illustrating scientific concepts. - Language used will be deliberately dense yet precise—employing terminology specific to fields like quantum mechanics or ethics without oversimplification. - Logical steps outlined will demand active deduction from readers; statements will be crafted such that conclusions aren't immediately obvious but require piecing together information logically spread throughout the text. ## Rewritten Excerpt In an alternate universe where Heisenberg's uncertainty principle dictates not just particles but historical causality itself—a realm where observing an event inherently alters its course—imagine Archimedes never discovering buoyancy due his infamous "Eureka!" moment being preemptively altered by a quantum observer effect induced paradoxically by his own anticipation of discovery years before actualization occurred; thus rendering him incapable of conceptualizing foundational principles governing fluid dynamics essential for naval warfare advancements during Syracuse’s siege by Marcellus’ forces circa Second Punic War era adjustments predicated upon Archimedes' hypothetical non-contribution towards hydrostatics principles; concurrently envision Einstein’s theory of relativity being formulated under conditions where temporal perception was nonlinearly variable due solely to gravitational waves emanating unpredictably from cosmic strings intersecting Earth’s orbit—an intersection causing sporadic shifts akin to temporal dilation effects observed near massive celestial bodies but instigated purely by quantum fluctuations rather than mass-induced spacetime curvature; juxtapose these theoretical alterations against Kantian ethics wherein categorical imperatives become mutable under circumstances dictated by observer-dependent reality frameworks thereby questioning moral absolutes within contextually fluid universes necessitating reevaluation of ethical axioms predicated upon deterministic versus probabilistic universe models. ## Suggested Exercise In an alternate universe governed by Heisenberg's uncertainty principle affecting historical events directly—a scenario wherein Archimedes' anticipation alters his discovery timeline due to quantum observation effects—how would Einstein's theory formulation differ under conditions influenced by unpredictable gravitational waves caused by cosmic strings intersecting Earth’s orbit? A) It would remain unchanged because Einstein’s theories are universally applicable regardless of temporal perception variations induced externally. B) It would adapt significantly since Einstein’s understanding would incorporate nonlinear temporal variables into relativity equations accounting for sporadic gravitational wave influences altering temporal perception akin to relativistic effects near massive celestial bodies but triggered by quantum fluctuations rather than mass-induced spacetime curvature alterations. C) It would be fundamentally flawed because Einstein could not reconcile his theories with phenomena that did not adhere strictly to Newtonian physics principles upon which his initial hypotheses were based. D) It would evolve into a theory exclusively focused on quantum mechanics disregarding general relativity due entirely attributable differences between observable macroscopic phenomena versus microscopic quantum effects influenced unpredictably by cosmic string intersections. *** Revision 1 *** check requirements: - req_no: 1 discussion: The draft lacks explicit connection requiring advanced external knowledge; it remains too speculative without anchoring questions directly into established, advanced academic content outside the excerpt itself. score: 1 - req_no: 2 discussion: Understanding subtleties appears necessary but could be more tightly linked with specific external knowledge areas like detailed physics concepts beyond basic principles mentioned. score: 2 - req_no: 3 discussion: While lengthy and complex language use meets this requirement well, making it difficult yet engaging without being overly convoluted could improve, ensuring clarity doesn't suffer beneath complexity. score: 2 - req_no: 4 discussion: Choices seem plausible but don't sufficiently challenge someone familiarized; they could better reflect nuanced understanding derived from both excerpt specifics and external academic facts. score: 1 - req_no: 5 discussion:The question poses difficulty yet falls short of truly challenging advanced-undergraduate-level; incorporating more nuanced academic content could elevate challenge appropriately. score :1' - req_no :6' discussion :Choices appear relevant but lack depth; integrating more sophisticated, nuanced distinctions among choices would prevent guesswork based solely on choice-plausibility.' score :1' external fact :Specific theories related directly impacting gravitational wave detection, such as LIGO/VIRGO collaborations' findings confirming predictions made by General Relativity, could provide concrete grounding needed.' revision suggestion :To satisfy requirements more fully,the exercise should integrate-specific-theoretical-knowledge-from-physics-and-history-beyond-basic-principles-discussed-in-the-excerpt.To-make-this-more-challenging-and-relevant,-the-question-could-explore-how-the-alternate-universe-scenarios-predicted-in-the-excerpt-would-affect-real-world-scientific-discoveries-or-historical-events-for-example,-linking-to-the-detection-of-gravitational-waves-by-LIGO/VIRGO-collaborations-and-comparing-these-findings-to-the-hypothetical-effects-of-cosmic-string-induced-gravitational-waves-on-Einstein's-theory-of-relativity-as-described.The-answer-options-could-refer-to-specific-aspects-of-general-relativity-or-historical-event-outcomes-that-would-be-different-under-these-alternate-scenarios.-This-not-only-demands-understanding-of-the-excerpt-but-also-deep-knowledge-of-general-relativity-and-historical-contexts,-ensuring-that-only-those-with-a-genuine-comprehension-can-select-the-correct-answer.' correct choice :'It would adapt significantly since Einstein’s understanding would incorporate nonlinear temporal variables into relativity equations accounting-for-sporadic-gravitational-wave-influences-altering-temporal-perception-akin-to-relativistic-effects-near-massive-celestial-bodies-but-triggered-by-quantum-fluctuations-rather-than-mass-induced-spacetime-curvature alterations.' revised exercise :"Considering the alternate universe described above where Heisenberg's uncertainty principle affects historical events directly—and assuming LIGO/VIRGO collaborations have detected gravitational waves consistent with those predicted under normal circumstances—how might these findings contrast against hypothetical observations made under conditions influenced uniquely by cosmic strings intersecting Earth’s orbit?

Rewritten Excerpt ## In an alternate dimension governed uniquely where Heisenberg's uncertainty principle extends beyond mere particles affecting entire historical narratives — imagine Archimedes' pivotal discovery never occurring because his anticipation paradoxically altered its timeline via a quantum observer effect years before its realization; thus incapacitating him from conceiving core fluid dynamics principles vital during Syracuse’s siege led by Marcellus’ forces around Second Punic War era adjustments hinging upon Archimedes’ non-existent contributions towards hydrostatics

spontaneously at points where cosmic strings intersect Earth’s orbit — causing random shifts similar temporally dilated effects seen near massive celestial entities yet initiated purely through quantum disturbances rather than traditional mass-driven spacetime warping; juxtapose these speculative modifications against Kantian ethical standards whereby categorical imperatives turn mutable
