I'm sorry, I thought I was more clear with my test case. Obviously, I was not.<div><br></div><div><br></div><div>The problem is this:</div><div><br></div><div> Python programs can call subprocesses. The python program can wait until the subprocess has finished and print the output captured. However, what we want is to print the output immediately as it is generated.</div>
<div><br></div><div> So, instead of waiting for the subprocess to finish, the python program could continue -- printing the results as given by the subprocess. From the way the test case is written, the communicate() method will wait until the subprocess is finished *before* it prints the results that were found.</div>

</div>Could you explain what the problem is? I think it's related to buffering<br>
and pipes, but it's not clear from your post.<br>
