使用管道与python

import re
import subprocess

sub = subprocess.Popen([\'/home/karthik/Downloads/stanford-parser-2011-06-   08/lexparser.csh\'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, stderr = subprocess.PIPE)

sub.stdin.write(\"i am a fan of ac milan which is the best club in the world\")

relns = []

while(True):
    rel = sub.stdout.readline()
        m = re.search(\"Sentence skipped\", rel)

    if m != None:
            print \'stop\'
            sys.exit(0)

        if rel == \'\\n\':
                break
        relns.append(rel) 

print relns

sub.terminate()
