将大量数据写入标准输入

为避免以可移植的方式出现死锁，请在单独的线程中写入子代：

#!/usr/bin/env pythonfrom subprocess import Popen, PIPEfrom threading import Threaddef pump_input(pipe, lines):    with pipe:        for line in lines: pipe.write(line)p = Popen(path, stdin=PIPE, stdout=PIPE, bufsize=1)Thread(target=pump_input, args=[p.stdin, lines]).start()with p.stdout:    for line in iter(p.stdout.readline, b''): # read output        print line,p.wait()

请参阅Python：从subprocess.communicate（）读取流输入
