Python使用subprocess模塊實現(xiàn)輸出的問題

1. def run_fail_test(test_list):
   
2. 297     for testcase in test_list.split(","):
   
3. 298        # os.system("/usr/bin/python "+testcase)
   
4. 299         command = "/usr/bin/python "+testcase
   
5. 300         print command
   
6. 301         #args = shlex.split(command)
   
7. 302        # print args
   
8. 303         children = subprocess.Popen(["/usr/bin/python",testcase],stdout=subprocess.PIPE)
   
9. 304         stdoutput = children.communicate
   
10. 305         if "Fail" in stdout :
    
11. 306           print "testcase have failed case,need to check!"
    
12. 307           exit(1)
    
13. 308         else :
    
14. 309           print "run testcase pass"
    
15. 310           return 0

但是最后還是報錯了，報錯內容如下：
Traceback (most recent call last):
xxxxxxxx(這里是調用的腳本import的一些信息）
    m = child.expect([self.newkeyPrompt, self.psswdPrompt, pexpect.EOF])
  File "/usr/lib/python2.4/site-packages/pexpect.py", line 1311, in expect
    return self.expect_list(compiled_pattern_list, timeout, searchwindowsize)
  File "/usr/lib/python2.4/site-packages/pexpect.py", line 1325, in expect_list
    return self.expect_loop(searcher_re(pattern_list), timeout, searchwindowsize)
  File "/usr/lib/python2.4/site-packages/pexpect.py", line 1378, in expect_loop
    c = self.read_nonblocking (self.maxread, timeout)
  File "/usr/lib/python2.4/site-packages/pexpect.py", line 841, in read_nonblocking
    self.logfile_read.flush()
IOError: [Errno 32] Broken pipe

["/usr/bin/python",testcase ]這是啥系統(tǒng)命令？/usr/bin/python 是不是漏了？
請參考

1. import os,sys,shlex,subprocess
   
2. from subprocess import *
   
3. i = 1
   
4. while i <= 99:
   
5.      input = "all_HC_genes_protein_"+str(i)+ ".fasta"
   
6.      filename = open(input,'r')
   
7.      handle = open(r'/export/data/orphans/1.txt','a+')
   
8.      proc = subprocess.Popen(["targetp","-P","-S","2","-c"],stdin=filename, stdout=handle)
   
9.      proc.wait()
   
10.      print i
    
11.      i += 1
