[Tutor] Queued threads

[Bernard Lebel]

Hello,

I have already messed a little with simple thread programming, wich took 
this form:


from threading import Thread

def mainFunction():
	pass

Thread( target=mainFunction ).start()


Now, I have a list of "jobs", each job being a windows bat file that 
launches an executable and performs a rendering task. So I have this 
queue of jobs, and would like to launch one only when the previous one 
has finished, and in a separate window. So far I have not been having 
much success with simple stuff:


from threading import Thread

def mainFunction():
     print 'function print'
     return 1

for i in range( 0, 3 ):
     oThread = Thread( target=mainFunction ).start()

     if oThread == 1:
             print 'sleeping 3 seconds'
             time.sleep( 3 )


In this example, 'sleeping 3 seconds' not returned, and each thread is 
started without any waiting.


I'm looking at the various threading module details in the library but I 
have to admit that, well, I'm a bit at loss here.


Thanks in advance
Bernard
