在子进程stdout中添加逗号

Question

python2.6-linux-centos6.7我有一个python脚本，可以实现我想要的东西。我使用子进程、UNIXfind和xargs来获取多个文件的md5sum。然后我把这个输出写到一个文件中，我遇到的问题是用逗号分隔哈希和文件名之间的空间。我尝试过拆分，但没有成功，还玩过csv模块。请建议：

parser = optparse.OptionParser()
parser.add_option('--searchpath', action="store", default="~", help="Enter your search path for files", type="string")
parser.add_option('--extension', action="store", default="*.php", help="Enter your file extension", type="string")
options, args = parser.parse_args()
if len(sys.argv[1:]) == 0:
    print "no argument given!"
    parser.print_help()
    sys.exit(1)
CMD = "/bin/find %s -name *.%s | xargs md5sum" % (options.searchpath,options.extension)
out = subprocess.Popen(CMD,shell=True,stdout=subprocess.PIPE,stderr=subprocess.PIPE)
(out,err) = out.communicate()
fp = open('logfile.txt','wb')
fp.write(out)
fp.close()

请查看输出：

期望结果：
