python 多线程并行化

import time
import threading
from concurrent.futures import ThreadPoolExecutor
#method对应于：自行编写的方法，可传参（可传多个参数，形如pool.submit(self.method, a,b)）
def method1():
	print("我是方法1")
def method2():
	print("我是方法2")
def method3():
	print("我是方法3")
def method4():
	print("我是方法4")
def method5():
	print("我是方法5")
def fun():
    start=time.time()
    # 创建包含5个线程的线程池
    pool = ThreadPoolExecutor(max_workers=5)
    future1 = pool.submit(method1)
    future2 = pool.submit(method2)
    future3 = pool.submit(method3)
    future4 = pool.submit(method4)
    future5 = pool.submit(method5)

    print("方法1结果：",future1.result())
    print("方法2结果：",future2.result())
    print("方法3结果：",future3.result())
    print("方法4结果：",future4.result())
    print("方法5结果：",future5.result())
    end=time.time()
    print("总耗时：",end-start)
    # 关闭线程池
    pool.shutdown()
fun()
