直接拿来用：进程&进程池&线程&线程池

# 1.1进程

from multiprocessing import Process
def fun(index):
    pass
if __name__ == '__main__':
    for i in range(10):
        p = Process(target=fun,args=(1,))
        p.start()

# 1.2进程池

from concurrent.futures import ProcessPoolExecutor
def fun(a,b):
    print(a,b)
if __name__ == "__main__":
    pool = ProcessPoolExecutor(10)
    pool.submit(fun,1,2)

# 2.1线程

from threading import Thread
def fun(index):
    pass
if __name__ == "__main__":
    t = Thread(target=fun,args=(1,))
    t.start()

# 2.2线程池

from concurrent.futures import ThreadPoolExecutor
def fun(a,b):
    print(a,b)
if __name__ == "__main__":
    tpool = ThreadPoolExecutor(10)
    tpool.submit(fun,1,2)
