Python CSV, blank rows

I'm trying to create a csv file with ping times. Below I have the code to get the ping time and put it in the csv file. Unfortunately the format in the csv files is a little messed up.

import subprocess as sp
import csv

ip = "216.52.241.254"
status,result = sp.getstatusoutput("ping -n 1 -w 1000 " + ip + ' | grep -o time=[0-9]* | grep -o [0-9]*')

with open('C:/PingData/test.csv', 'a') as csvfile:
    #result = int(result)
    cwriter = csv.writer(csvfile, delimiter=' ', quotechar='|', quoting=csv.QUOTE_MINIMAL)
    cwriter.writerow(result)

The csv file that this code is printing looks like:

What it should look like is this:

I'm looking for a solution/reason why there are extra blank rows being printed, and why there are spaces between the numbers (I've tried passing them in as integers to no avail)
