Scenario

I tried to run a function "foo" every second. I have to do this for a few minutes (say 5).

The function foo () sends 100 HTTP requests (including JSON objects) to the server and prints the JSON response.

In short, I have to issue 100 HTTP requests per second for 5 minutes.

Using threading.Timer

#!/usr/bin/python
import time
import thread
import threading

def foo():
    print time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time())), threading.active_count()

#5 minutes = 5 * 60 = 300 seconds
for x in range(0, 300):
    t = threading.Timer(x + 1, foo)
    t.start()

Expected output

function foo was executed per second and last about 5 minutes
