Python中的for循环多处理

Question

我想并行执行for循环。 我怎样才能做到这一点？

例如：

def foo():
    # brahbrah

for i in range(0,5):
    foo()

谢谢

Answer 1

from multiprocessing import Pool
from multiprocessing import cpu_count


def foo():
    # brahbrah

def func(count):
    foo()

if __name__ == "__main__":
    pool = Pool(cpu_count())
    count = 5
    results = pool.map(func, range(count))
    pool.close()  # 'TERM'
    pool.join()   # 'KILL'
