python - 如何重复调用一个函数？

Question

通过模块multiproproccessing.dummy , 我要执行函数getData() 10次​​。但是，print函数只调用一次。

from multiprocessing.dummy import Pool as ThreadPool

print("Begin")

import itertools
import urllib.request
import time

def getData():
        print("Do something...")

t0 = time.time()
with ThreadPool(10) as pool:
    results = pool.map_async(getData(), iterable=(x for x in range(10)))
    
t1 = time.time()
totalTime = t1-t0
print ("Total Cyclic time: ", totalTime)   

Answer 1

您调用getData()在将其传递给 map_async 之前，它传递它的结果，而不是传递函数本身。
更改getData()至getData你应该没事。

    results = pool.map_async(getData, ...)
