python进程池和线程池

from concurrent.futures import ThreadPoolExecutor, ProcessPoolExecutor

# 线程池
# def target(url):
	# print(url)

# def main():
# 	# 创建线程池
# 	with ThreadPoolExecutor(30) as t:
# 		for url in range(100):
# 			t.submit(target, url)

# 	# 主线程等待线程池所有线程执行完成
# 	print("主线程...")

# 进程池
def target(url):
	print(url)


def main():
	# 创建进程池
	with ProcessPoolExecutor(30) as t:
		for url in range(1000):
			t.submit(target, url)

	# 主进程等待线程池所有进程执行完成
	print("主进程...")
