Get stdout output as list of dictionary instead of string

Question

I'm running a python script with subprocess, which will in turn run another test.py script and get some output.

test.py , does some parsing and outputs the list of dictionaries.

  data = [{'a': 12, 'name':'abc'}, {'a': 16, 'name':xyz}, {'a': 17, 'name': lmn}]

  def func1:
  cmd = 'python {}{}{} {} {}'.format(settings.BASE_DIR,'test.py',arg1,arg2)
  p = subprocess.Popen(cmd, stdout=subprocess.PIPE, stderr=subprocess.PIPE, shell=True)
  out, err = p.communicate()
  return(p.returncode,err, out)

  def funct2(request):
    if request.GET:
        statuscode,err,resp = func1(arg1,arg2)       
        if not err and statuscode == 0:
             return HttpResponse(json.dumps({'resp':resp,'status_code':statuscode,'err':err}),content_type="application/json")

So that i can handle this data in my javascript to get json object. As of now in my .js file its coming has string even after JSON.parse(resp)

My question is how do i send output of test.py as a list only and handle it further to get a JSON object in my javascript as shown below.

use pickle. refer this https://docs.python.org/2/library/pickle.html — Veera Balla Deva, Jan 25 '18 at 12:57
@Pradam can you be more specific on where to i use pickle here before writing it to sys.stdout.write(str(data)) ? or later — Rachel, Jan 25 '18 at 13:09
@Rakesh No data is a list of dict. data = [{'a': 12, 'name':'abc'}, {'a': 16, 'name':xyz}, {'a': 17, 'name': lmn}]. If i try to return data as it is it throws error. — Rachel, Jan 25 '18 at 13:49
@Pradam sorry it does not throw any error but out, err = p.communicate() out is empty — Rachel, Jan 25 '18 at 14:06
@Rachel if you put more code it will be more useful so can able to rectify what's happening. — Veera Balla Deva, Jan 25 '18 at 14:21
@Pradam i have edited the question and added some code hope it helps — Rachel, Jan 25 '18 at 14:38

@Pradam it is not much of use. Is it possible to change subprocess.popen() output to list — Rachel, Jan 27 '18 at 07:40
