The last five columns are particularly important as they hold values needed for aggregation (`unique` and `multiply`). Students must carefully handle cases where lines might not conform exactly to this format. 2. **Handling Comments**: Lines beginning with `#` are comments that should be ignored. This requires correctly identifying such lines without processing them further. 3. **Dynamic Dictionary Handling**: The `counts` dictionary dynamically updates based on whether a sample already exists within it or not. This involves conditional logic to either initialize or update entries. 4. **Data Conversion**: Converting string representations of numbers into integers requires error handling in case any unexpected non-numeric data appears. 5. **Performance Considerations**: Efficiently processing potentially large files without excessive memory usage or slowdowns. ### Extension 1. **File Format Variations**: Handle different file formats or delimiters (e.g., commas instead of tabs). This would require detecting or specifying the delimiter dynamically. 2. **Error Handling**: Implement robust error handling for various anomalies like missing columns, non-integer values where integers are expected, etc. 3. **Multiple Files**: Extend functionality to process multiple files from a directory instead of just one file. 4. **Real-time Processing**: Handle files being added or modified during processing. 5. **Data Validation**: Add checks to ensure data integrity before processing. ## Exercise ### Problem Statement You are required to extend the functionality provided in [SNIPPET]. Your task includes handling multiple input files from a directory specified via command-line arguments and supporting different delimiters (tabs or commas). Additionally, implement robust error handling mechanisms for missing columns or non-numeric data entries. **Requirements**: 1. **Input Directory**: The script should take an input directory containing multiple files. 2. **Delimiter Detection**: Automatically detect whether each file uses tabs or commas as delimiters. 3. **Error Handling**: Gracefully handle cases where lines do not have enough columns or contain non-integer values where integers are expected. 4. **Output Summary**: After processing all files, output a summary showing total `unique` and `multiply` counts per sample across all files. ### Provided Code Snippet python def get_counts(file): counts = {} for line in file: if line.startswith("#"): continue tokens = line.split("t") sample = tokens[-1] unique = int(tokens[-4]) multiply = int(tokens[-5]) if sample not in counts: counts[sample] = [unique,multiply] else: counts[sample][0] += unique counts[sample][1] += multiply return counts ### Solution python import os import argparse def detect_delimiter(line): if ',' in line: return ',' else: return 't' def get_counts(file_path): counts = {} with open(file_path) as file: delimiter = detect_delimiter(file.readline()) file.seek(0) # Reset file pointer after reading first line for line in file: if line.startswith("#"): continue tokens = line.strip().split(delimiter) try: sample = tokens[-1] unique = int(tokens[-4]) multiply = int(tokens[-5]) except (IndexError, ValueError) as e: print(f"Skipping invalid line in {file_path}: {line.strip()} ({e})") continue if sample not in counts: counts[sample] = [unique,multiply] else: counts[sample][0] += unique counts[sample][1] += multiply return counts def process_directory(directory): total_counts = {} for filename in os.listdir(directory): if filename.endswith(".txt"): # Assuming .txt files; can adjust based on requirements. file_path = os.path.join(directory, filename) file_counts = get_counts(file_path) for sample in file_counts: if sample not in total_counts: total_counts[sample] = [file_counts[sample][0], file_counts[sample][1]] else: total_counts[sample][0] += file_counts[sample][0] total_counts[sample][1] += file_counts[sample][1] return total_counts def main(): parser = argparse.ArgumentParser(description='Process read count data from files.') parser.add_argument('directory', type=str, help='Directory containing input files') args = parser.parse_args() summary_counts = process_directory(args.directory) print("Summary Counts:") print("SampletUniquetMultiply") for sample in sorted(summary_counts.keys()): print(f"{sample}t{summary_counts[sample][0]}t{summary_counts[sample][1]}") if __name__ == "__main__": main() ## Follow-up exercise ### Problem Statement Enhance your solution by adding real-time processing capabilities: 1. Continuously monitor the input directory for new files added during execution. 2. Process these new files as they appear without restarting the script. 3. Implement multi-threading or asynchronous processing to handle large volumes efficiently. **Requirements**: 1. Use appropriate libraries like `watchdog` for monitoring directory changes. 2. Ensure thread safety when updating shared resources like `total_counts`. 3. Maintain performance efficiency even with concurrent file additions. ### Solution python import os import argparse import threading from watchdog.observers import Observer from watchdog.events import FileSystemEventHandler class FileHandler(FileSystemEventHandler): def __init__(self): self.lock = threading.Lock() self.total_counts = {} def detect_delimiter(self,line): if ',' in line: return ',' else: return 't' def get_counts(self,file_path): counts = {} with open(file_path) as file: delimiter=self.detect_delimiter(file.readline()) file.seek(0) # Reset file pointer after reading first line for line in file: if line.startswith("#"): continue tokens=line.strip().split(delimiter) try: sample=tokens[-1] unique=int(tokens[-4]) multiply=int(tokens[-5]) except (IndexError, ValueError) as e: print(f"Skipping invalid line in {file_path
