weakref.getweakrefcount(object) Return the number of weak references and proxies which refer to object.

__call__() If self is alive then mark it as dead and return the result of calling func(*args, **kwargs). If self is dead then return None.

peek() If self is alive then return the tuple (obj, func, args, kwargs). If self is dead then return None.

detach() If self is alive then mark it as dead and return the tuple (obj, func, args, kwargs). If self is dead then return None.

atexit A writable boolean property which by default is true. When the program exits, it calls all remaining live finalizers for which atexit is true. They are called in reverse order of creation.

alive Property which is true if the finalizer is alive, false otherwise.

class weakref.finalize(obj, func, *args, **kwargs) Return a callable finalizer object which will be called when obj is garbage collected. Unlike an ordinary weak reference, a finalizer will always survive until the reference object is collected, greatly simplifying lifecycle management. A finalizer is considered alive until it is called (either explicitly or at garbage collection), and after that it is dead. Calling a live finalizer returns the result of evaluating func(*arg, **kwargs), wher

weakref.CallableProxyType The type object for proxies of callable objects.

Wave_write.writeframesraw(data) Write audio frames, without correcting nframes. Changed in version 3.4: Any bytes-like object is now accepted.

Wave_write.writeframes(data) Write audio frames and make sure nframes is correct. It will raise an error if the output stream is not seekable and the total number of frames that have been written after data has been written does not match the previously set value for nframes. Changed in version 3.4: Any bytes-like object is now accepted.
