subprocess.call logger info and error for stdout and stderr

I have a logger. I am calling an external process. I capture stdout and stderr seperatly from that process so that I can log them.

I have this error:

Traceback (most recent call last): File "importData.py", line 198, in importData(ftpServerName,ftpU,ftpP,directory,filematch,source,destination) File "importData.py", line 99, in importData p = subprocess.Popen(['mongoimport --db AutoPrivilege -c cars stockvo.json --jsonArray --upsert --drop'], stdout=subprocess.PIPE, stderr=subprocess.PIPE) File "/usr/lib/python2.7/subprocess.py", line 710, in init errread, errwrite) File "/usr/lib/python2.7/subprocess.py", line 1335, in _execute_child raise child_exception OSError: [Errno 2] No such file or directory

my script:

...
        #import json file to MongoDB
        logger.info(' Import json file to MongoDB')
        #subprocess.call('mongoimport --db AutoPrivilege -c cars stockvo.json --jsonArray --upsert --drop',shell=True)
        p = subprocess.Popen(["mongoimport --db AutoPrivilege -c cars stockvo.json --jsonArray --upsert --drop"], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
        stdout, stderr = p.communicate()

        if stdout:
            logger.info(stdout)
        if stderr:
            logger.error(stderr)
...

Is there a way to resolved that?

subprocess.Popen constructor accepts list of args, not string:

p = subprocess.Popen(['mongoimport', '--db', 'AutoPrivilege', '-c',
                      'cars', 'stockvo.json', '--jsonArray', '--upsert',
                      '--drop'])...
