使用ThreadPoolExecutor执行任务，来统计显示执行进度，执行耗时
from concurrent.futures import ThreadPoolExecutor, as_completed
import time
import uuid
def vm_one(uuid ,start_time):
time.sleep(1)
global c
global total
c = c+1
print("index:{}/{},value:{},time:{:.3f}".format(c,total,uuid,time.time()-start_time))
return uuid
if __name__ == '__main__':
start_time = time.time()
c = 0
uuids = [uuid.uuid4() for _ in range(0,100)]
total = len(uuids)
with ThreadPoolExecutor(max_workers=10) as pool:
all_task = [pool.submit(vm_one, uid,start_time) for uid in uuids]
all_data = []
for out in as_completed(all_task):
mess = out.result()
all_data.append(mess)
输出结果：
