Oops, you probably want to do this then-
for i in range( 0, 3 ):
oThread = Thread( target=mainFunction ).start()
while oThread:
print 'sleeping 3 seconds'
time.sleep( 3 )
A if <condition> generally has an implicit else: pass clause as I
think of it, so it will just keep reiterating if the condition isn't
met.
To see what I mean try -
for i in range(5):
#The 0 is default starting for range function
if i==15:
print 'fifteen'
print i
You'll, of course, get
0
1
2
3
4
It won't wait until i equals 15.
on the other hand -
for i in range(5):
while i != 15:
print "nope"
print i
You'll get a runaway while, and 'nope' will cascade down your stream,
and you'll have great trouble closing Python. But i will never get
printed, as it will still be waiting for i to equal fifteen.

'There is only one basic human right, and that is to do as you damn well please.
And with it comes the only basic human duty, to take the consequences.
