Write a self-contained Python program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,":1, "an":1, "example":1} The program should be run by calling /path/to/python_word_count with no arguments. Make it run in parallel on 4 cores at the same time, each taking 1/4 of the file. Print out 4 differnt json dicts, one per line. I'll do the merging.

Here's a self-contained Python program that meets your specifications. It reads a text file located at `/tmp/file.txt`, counts the frequency of each word in parallel using 4 processes, and prints the JSON output of word counts as separate dictionaries on different lines. You can save this code in a file named `python_word_count.py`.

To achieve the desired functionality of counting word occurrences in a text file using parallel processing, we can use Python's `concurrent.futures` module. Below is a self-contained Python program that reads a text file, splits its content into four parts, and processes each part in parallel to count the occurrences of each word. Finally, it outputs the results as JSON dictionaries. Here's the Python code:

Write a self-contained Python program that prints a JSON output of how often each word appears in a text file located in /tmp/file.txt. So if the file contains "This is is is, an example" then the program should print to stdout. {"This": 1, "is": 2, "is,":1, "an":1, "example":1} The program should be run by calling /path/to/python_word_count with no arguments. Make it run in parallel on 4 cores at the same time, each taking 1/4 of the file. Print out 4 differnt json dicts, one per line. I'll do the merging.

To create a self-contained Python program that counts the frequency of words in a text file using parallel processing, we can use the `concurrent.futures` module to handle the parallel execution. Below is an implementation that divides the file into four parts, counts the words in each part, and then prints the results as JSON dictionaries. Here's the complete code for the program:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | import json import os from concurrent.futures import ProcessPoolExecutor from collections import Counter def count_words_in_chunk(chunk): """Count the frequency of words in a given text chunk.""" words = chunk.split() return Counter(words) def read_file_in_chunks(file_path, num_chunks): """Read the file and yield its content in chunks.""" with open(file_path, 'r') as file: content = file.read() chunk_size = len(content) // num_chunks for i in range(num_chunks): start = i * chunk_size end = None if i == num_chunks - 1 else (i + 1) * chunk_size yield content[start:end] def main(): file_path = '/tmp/file.txt' num_chunks = 4 # Prepare to process the chunks in parallel with ProcessPoolExecutor(max_workers=num_chunks) as executor: results = list(executor.map(count_words_in_chunk, read_file_in_chunks(file_path, num_chunks))) for result in results: print(json.dumps(result)) if __name__ == '__main__': main() |
1 | /path/to/python_word_count.py |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 | import json import os from concurrent.futures import ProcessPoolExecutor from collections import Counter def count_words_in_chunk(chunk): """Count the frequency of words in a given text chunk.""" words = chunk.split() return Counter(words) def read_file_in_chunks(file_path, num_chunks): """Read the file and yield its content in chunks.""" with open(file_path, 'r') as file: content = file.read() chunk_size = len(content) // num_chunks for i in range(num_chunks): start = i * chunk_size end = None if i == num_chunks - 1 else (i + 1) * chunk_size yield content[start:end] def main(): file_path = '/tmp/file.txt' num_chunks = 4 # Prepare to process the chunks in parallel with ProcessPoolExecutor(max_workers=num_chunks) as executor: results = list(executor.map(count_words_in_chunk, read_file_in_chunks(file_path, num_chunks))) for result in results: print(json.dumps(result)) if __name__ == '__main__': main() |

To accomplish the task of counting the frequency of each word in a text file using parallel processing, we can use the `concurrent.futures` module in Python. The following program reads the file, splits it into 4 chunks, processes each chunk using a separate thread, and then prints the JSON output for each chunk. Here's how you can implement it:
