如何在python中并行化嵌套的for循环？

import concurrent.futures

def nested_loop(i, j):
    # 嵌套循环的逻辑
    # 这里只是一个示例，你可以根据实际需求编写自己的逻辑
    result = i + j
    return result

def parallel_nested_loop():
    # 定义嵌套循环的范围
    outer_range = range(10)
    inner_range = range(5)

    # 创建线程池
    with concurrent.futures.ThreadPoolExecutor() as executor:
        # 提交任务到线程池
        futures = [executor.submit(nested_loop, i, j) for i in outer_range for j in inner_range]

        # 获取并行计算的结果
        results = [future.result() for future in concurrent.futures.as_completed(futures)]

    # 打印结果
    print(results)

# 调用并行化嵌套循环的函数
parallel_nested_loop()
