Python : How to run a function "foo" per second and last a few minutes or hours

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
