ProcessPoolExecutor 和 ThreadPoolExecutor 有什么区别

ProcessPoolExecutor和ThreadPoolExecutor的区别

python
import concurrent.futures
# 使用ThreadPoolExecutor执行并发任务
def thread_task(n):
    print(f"Thread task {n} started")
    result = n * 2
    print(f"Thread task {n} finished, result: {result}")
    return result
with concurrent.futures.ThreadPoolExecutor() as executor:
    # 提交5个任务给线程池
    results = [executor.submit(thread_task, i) for i in range(5)]
    # 获取任务的执行结果
    for future in concurrent.futures.as_completed(results):
        result = future.result()
        print(f"Thread task result: {result}")
# 使用ProcessPoolExecutor执行并发任务
def process_task(n):
    print(f"Process task {n} started")
    result = n * 2
    print(f"Process task {n} finished, result: {result}")
    return result
with concurrent.futures.ProcessPoolExecutor() as executor:
    # 提交5个任务给进程池
    results = [executor.submit(process_task, i) for i in range(5)]
    # 获取任务的执行结果
    for future in concurrent.futures.as_completed(results):
        result = future.result()
        print(f"Process task result: {result}")
