Project description
Util Process Pool
简便的多进程调用工具,基于 concurrent.futures.ProcessPoolExecutor 的封装。
特性
- 🚀 简化的多进程调用接口
- 📊 进度跟踪和错误处理
- 🔧 灵活的配置选项
- 📝 详细的日志记录
- 🎯 支持多种任务类型(CPU密集型、IO密集型)
安装
pip install util-process-pool
快速开始
基本使用
from util_process_pool import parallel_map
# 简单的并行计算
numbers = list(range(10))
results = parallel_map(lambda x: x * x, numbers)
print(results) # [0, 1, 4, 9, 16, 25, 36, 49, 64, 81]
使用 ProcessPool 类
from util_process_pool import ProcessPool
def process_data(data):
# 处理数据的函数
return data * 2
with ProcessPool(max_workers=4) as pool:
data_list = [1, 2, 3, 4, 5]
results = list(pool.map(process_data, data_list))
print(results) # [2, 4, 6, 8, 10]
批量执行复杂任务
from util_process_pool import batch_execute
def complex_task(param1, param2):
# 复杂的处理逻辑
return f"Processed: {param1} + {param2}"
# 准备参数列表
args_list = [
(("hello", "world"),), # 第一个任务
(("foo", "bar"),), # 第二个任务
]
results = batch_execute(complex_task, args_list, show_progress=True)
API 文档
ProcessPool 类
主要的进程池管理类。
ProcessPool(
max_workers=None, # 最大工作进程数(默认:CPU核心数)
initializer=None, # 进程初始化函数
initargs=(), # 初始化函数参数
logger=None # 自定义日志记录器
)
方法:
submit(func, *args, **kwargs): 提交单个任务map(func, iterable, timeout=None, chunksize=1): 并行映射execute_batch(func, args_list, timeout=None, show_progress=False): 批量执行wait_completion(timeout=None): 等待所有任务完成
工具函数
parallel_map(func, iterable, max_workers=None, chunksize=1, timeout=None)batch_execute(func, args_list, max_workers=None, timeout=None, show_progress=False)
