No, this list is not a linked list. Since mu original code is rather huge, I am presenting the relevant snippet. queue=[] def genpassenger(num,destination,queue=queue): for i in range(num): newpass=passenger(destination) queue.append(newpass) newpass.start() class passenger(threading.Thread): def __init__ <snip> def run: #do something delete itself
genpassengers is called interactively by the user .Also there can be multiple instances of genpassengers running at the same time. Now my questions are: 1) Generically , how do i accomplish the delete itself part
In the code you have shown, I don't see any need for the queue. Just create the thread and start it. I don't think you have to keep a reference to it. I'm not sure, but I think the thread will be garbage collected when it completes. (Can anyone else confirm this?)
2) If i used a linked list, does automatic memory handling by python entail that delete itself is automatically accomplished once i have readjusted the pointers, since no further reference to the instance remains.(Of course, if it doesnt i can get a reference in the external code(in case of a doubly linked list)).
Yes. When there is no remaining reference to an item it is garbage collected.
3) How about making a destructor function (on lines of c++) and deleting all the variables of the class.Does it free all my memory or is there still some memory being used, though the instance has no variables stored.
This is not needed. When a class is GCed then everything it references will also be GCed, unless something else still retains a reference to it.
