yutilx 0.0.3

Xinyu's common utilities

yutilx

A Python utilities library providing efficient parallel processing with caching capabilities.

Features

• Parallel Processing: Execute functions concurrently using ThreadPoolExecutor
• Smart Caching: Automatic result caching with MD5-based deduplication
• Flexible Storage: Choose between file-based (JSONL) or in-memory caching
• Retry Logic: Built-in retry mechanism for handling transient failures
• Progress Tracking: Real-time progress visualization with tqdm
• Thread-Safe: Safe concurrent access to cache

Installation

pip install yutilx

Quick Start

from yutilx import CachedParallelProcessor

# Define your processing function
def process_text(text: str) -> str:
    # Your processing logic here
    return text.upper()

# Create a processor instance
processor = CachedParallelProcessor(
    process_func=process_text,
    max_retry_cnt=3,
    cache_filename="results.jsonl"
)

# Process data in parallel
inputs = ["hello", "world", "python", "rocks"]
processor.run(inputs, num_threads=4)

# Retrieve results
results = processor.get_result(inputs)
print(results)  # ['HELLO', 'WORLD', 'PYTHON', 'ROCKS']

API Reference

CachedParallelProcessor

CachedParallelProcessor(
    process_func: Callable[[str], str],
    max_retry_cnt: int = 3,
    cache_filename: Optional[str] = None,
    cache_file_free: bool = False
)

Parameters

• process_func: Function to process each input string
• max_retry_cnt: Maximum retry attempts for failed processing (default: 3)
• cache_filename: Path to cache file (default: "cache.jsonl")
• cache_file_free: If True, use in-memory cache only (default: False)

Methods

• run(input_lis: list[str], num_threads: int = 10): Process inputs in parallel
• get_result(input_lis: list[str]) -> list[str]: Retrieve cached results
