multithreading - Python daemon thread does not exit when parent thread exits -


I have some python code which creates a monster thread parent's thread ends almost immediately, but Damon Thread The print keeps sleeping. 

  Import threading import time_date (): _ (1, 600) for category: time.sleep (1) print ("sleep") def main (): thread = threading . Thread (target = int_sleep) thread.daemon = True thread.start () time.sleep (2) print ("main thread end ...") thread = threading. Thread (target = main) thread Start ()

sys.version: 

  '3.3.3 (v3.3.3: c3896275c0f6, November 18, 2013, 21:19:30) [ MSc v.1600 64bit (AMD64)] '

Prints: 

  The main thread of gold end .. 
  < / Div> 
 
   = "text"> 
 If you want to  thread.daemon = True , the program will only close when the daemon is left only. The commands sent to Stdout are lost. 
 
 main.py 
 
  import At the time of importing, def int_sleep (): Add it to a file named (Category: 1, 600): time.sleep ( 1) Print ("sleep") def main (): thread = threading. Thread (target = int_sleep) thread.daemon = True thread.start () time.sleep (2) Print ("main thread end ...") Thread = Threading. Thread (target = main) thread.daemon = True thread.start ()  
 
 Run it like this: 
 
  el @ apollo: ~ / Code / Python / run01 $ python --version Python 2.7.6 L @ Apollo: ~ $ Python main.py l Apollo: ~ $  
 
 It does not print anything because the thread is started. You have set it to a daemon and it has started. Then the program ended. 
 
 Additional Notes: If you paste this code into a dragon interpreter, then all print statements will appear on the terminal because the daemon never loses its connection with stdout.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
