如何使用多进程进行1000次模拟

import multiprocessing

def simulate(n):
    # 模拟任务代码
    # ...

pool = multiprocessing.Pool()

for i in range(1000):
    pool.apply_async(simulate, args=(i,))

pool.close()

pool.join()

import multiprocessing

def simulate(n):
    # 模拟任务代码
    # ...

if __name__ == '__main__':
    pool = multiprocessing.Pool()
    for i in range(1000):
        pool.apply_async(simulate, args=(i,))
    pool.close()
    pool.join()
