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
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)).
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.
