How to determine latency of a GET request, in python

import subprocess

host = "yahoo.com"

ping = subprocess.Popen(
    ["ping", "-c", "3", host],
    stdout = subprocess.PIPE,
    stderr = subprocess.PIPE
)

out, error = ping.communicate()
print out

So far I have this for a ping test to a server

basically:

Take a look at this,

Everytime I look want to look up prices of products, i send a HTTP GET request with the product details to f3's API. I am trying to determine how long it takes to retrieve the product price information after receiving my call.

If you need only HTTP ping, you can use the excellent Python library, requests

import requests, json

def call_some_api (params) :
    """ You can track time of any your API call. """

    result = requests.get("rest-api-endpoint.com")
        # Now result contains all request data you need


    print "Call time:", result.elapsed # .. prints timedelta ..
    json_result = json.load( result.text ) # Here are RESTful API, JSON response

    return json_result

For more information you can see requests docs

If you looking for timing some action in general, you can use this simple decorators

For current python, use print(f'Call time: {result.elapsed}')

Optionally, use result.elapsed.total_seconds()

See How to measure server response time for Python requests POST-request

I'm not sure I understand your question well, but if I'm right, what you want can be achieved using the time function from the time module, which returns the number of seconds elapsed since EPOCH:

from time import time

time_before = time()
perform_get() # whatever way you do this
time_after = time()
time_taken = time_after-time_before

print time_taken
