Queuing the file content and run the thread.

[pythonlover]

Hello,
I have a list of network devices in a file (each line is a device). I am passing each device or each line of that file as an argument to a curl statement to get the interfaces from the devices. The problem is, since there are more than 20K devices - it is actually taking a lot of time to get all the interfaces. 
This led me into threading and queuing module. Now, I am queuing all the devices and then running the thread. The thread contains the function to pull the interfaces. 

with open("filtered_devices") as my_file:
   for line in my_file:
     q.put(line)

numofThreads = 10.
for i in range (numofThreads):
   print str(threading.activeCount())
   t = threading.Thread(target = queue_interfaces())
   t.start()
   #threadlist.append(t)

Here, queue_interfaces() is the function that passes each devices as as argument and gets the interfaces. Not sure if this is the correct way to do that. May be I am doing it wrong, since the time is still the same. Can somebody please advise?
Also, my active thread count is not incrementing.
