无法在此python代码中放入多线程逻辑

Question

有没有办法在这里使用多线程，因此如果创建了4个节点，文件将并行发送到4个节点。

#!/usr/bin/python2

import os

x = raw_input("Enter no. of nodes you want to create: ")
print "\nEnter ip as follows -- 1 192.168.0.1 \n"
d = dict(raw_input().split() for _ in range(int(x)))

for i in d:
    os.system("sshpass -p 'abc@abc' scp /root/Desktop/abc.py root@" + d[i] 
+":/root/Desktop/md/")
    print "configured successfully " + i
