python multiprocessing does not run at same time -


i trying make python program runs multiple processes each in infinite loop @ same time, 1 process execute @ time, first 1 in code, rest of program not run. need make both procceses , main 1 execute @ same time?

from multiprocessing import * import time   def test1(q):     while true:         q.put("banana")         time.sleep(2)    def test2(q):     while true:         q.put("internet")         time.sleep(3)   if __name__ == "__main__":      q = queue()      t1 = process(target=test1(q))      t2 = process(target=test2(q))      t1.start()      t2.start()      q.put("rice")      while true:          print(q.get())

the reason problem lines:

     t1 = process(target=test1(q)      t2 = process(target=test2(q)

there call test1 , test2, respectively (even though never reach test2 call. after running functions use return result target. want is:

     t1 = process(target=test1, args=(q,))      t2 = process(target=test2, args=(q,))

thus, not want run test1 , test2functions, use references (addresses) target , have provide there input arguments in separate parameter args.

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m
