Im trying to list a folder of pdf files in html page so that user can download them. I'm able to do this for a single file, but not sure on how to do for a folder. :(

My view is :

def plot_graph_single_fsn(request):

    payload = {"fsns": "values",
               "signals": "signals",
               "responseFormat": "csv"
               }
    response_data = requests.post(post_api, data=json.dumps(payload))
    # Writing response to csv file
    temp_file_name = 'temp_csv.csv'
    with open(temp_file_name, 'w') as temp_file:
        temp_file.writelines(response_data.content.decode('utf-8'))

    # calling script that generated pdf folder from csv 
    csv_file = os.path.abspath('tmp.csv')
    util_path = os.getcwd()
    process = subprocess.Popen(['python', util_path + '/Utils/' + 'tmp.py', csv_file],
                               stdout=subprocess.PIPE)
    a, err = process.communicate()
    print "\n"
    return HttpResponse(folder_path)
