Quick Python Q, parameter passing interpretation help needed


This python code has a (,) segment  t = Thread(target=myfunc, args=(i,))

what does the (,)) mean? precisely one argument passed in? No second argument?

import time
from threading import Thread

def myfunc(i):
    print "sleeping 5 sec from thread %d" % i
    print "finished sleeping from thread %d" % i

for i in range(10):
    t = Thread(target=myfunc, args=(i,))

|      *args* is the argument tuple for the target invocation. Defaults to ().
This means that it expects arts to be a tuple.  Since only one value is supplied, it requires the comma
