python交互式输入-使用python进行交互式输入/输出

我有一个与用户交互的程序(就像一个shell),我希望以交互方式使用python子进程模块运行它.

这意味着,我希望有可能写入stdin并立即从stdout获取输出.我在这里尝试了许多解决方案,但它们似乎都不能满足我的需求.

import Queue

import threading

import subprocess

def enqueue_output(out, queue):

for line in iter(out.readline, b""):

queue.put(line)

out.close()

def getOutput(outQueue):

outStr = ""

try:

while True: #Adds output from the Queue until it is empty

outStr+=outQueue.get_nowait()

except Queue.Empty:

return outStr

p = subprocess.Popen("./a.out", stdin=subprocess.PIPE, stout=subprocess.PIPE, stderr=subprocess.PIPE, bufsize = 1)

#p = subprocess.Popen("./a.out", stdin=subprocess.PIPE, stout=subprocess.PIPE, stderr=subprocess.PIPE, shell=False, universal_newlines=True)

outQueue = Queue()

errQueue = Queue()

outThread = Thread(ta
