Thread objects corresponding to “alien threads”, which are threads of control There is the possibility that “dummy thread objects” are created. There is a “main thread” object this corresponds to the initial thread ofĬontrol in the Python program. Use a suitable signalling mechanism such as an Event. If you want your threads to stop gracefully, make them non-daemonic and Their resources (suchĪs open files, database transactions, etc.) may not be released properly. Through the daemon property or the daemon constructorĭaemon threads are abruptly stopped at shutdown. Initial value is inherited from the creating thread. That the entire Python program exits when only daemon threads are left. Threading.excepthook() ignores silently SystemExit.Ī thread can be flagged as a “daemon thread”. Threading.excepthook() is called to handle it. The name can be passed to the constructor, and read or The calling thread until the thread whose join() method isĪ thread has a name. Other threads can call a thread’s join() method. Method tests whether the thread is alive. Normally, or by raising an unhandled exception. Stops being alive when its run() method terminates – either Once the thread’s activity is started, the thread is considered ‘alive’. Once a thread object is created, its activity must be started by calling the _init_() and run() methods of this class. No other methods (except for the constructor) should be There are two ways to specify the activity: by passing aĬallable object to the constructor, or by overriding the run() The Thread class represents an activity that is run in a separate Specifying a timeout greater than this value will raise an ( Lock.acquire(), RLock.acquire(), Condition.wait(), etc.). The maximum value allowed for the timeout parameter of blocking functions This module also defines the following constant: threading. The suggested approach in the absence of more specific information).Īvailability: Windows, systems with POSIX threads.

Size argument specifies the stack size to be used for subsequently created Return the thread stack size used when creating new threads. Hook completes to avoid resurrecting objects. Storing thread using a custom hook can resurrect it if it is set to an Should be cleared explicitly to break the reference cycle when the Storing exc_value using a custom hook can create a reference cycle. Threading.excepthook() can be overridden to control how uncaughtĮxceptions raised by n() are handled. If this function raises an exception, sys.excepthook() is called to Otherwise, the exception is printed out on sys.stderr. If exc_type is SystemExit, the exception is silently ignored. Thread: Thread which raised the exception, can be None.
The args argument has the following attributes:Įxc_traceback: Exception traceback, can be None. The function currentThread is a deprecated alias for this function. Threading module, a dummy thread object with limited functionality is If the caller’s thread of control was not created through the Return the current Thread object, corresponding to the caller’s thread The function activeCount is a deprecated alias for this function. The returnedĬount is equal to the length of the list returned by enumerate(). Return the number of Thread objects currently alive. This module defines the following functions: threading. However, threading is still an appropriate model if you want to run Resources of multi-core machines, you are advised to use If you want your application to make better use of the computational Libraries might overcome this limitation).
