The .__init__() method must store a reference to the function, and it can do any other necessary initialization. The .__call__() method will be called instead of the decorated function. It does essentially the same thing as the wrapper() function in your earlier examples. Note that ...
A socket function or method that temporarily suspends your application is a blocking call. For example, .accept(), .connect(), .send(), and .recv() block, meaning they don’t return immediately. Blocking calls have to wait on system calls (I/O) to complete before they can return a va...

All functions and classes have a call() method, hence are callable. Use 'callable(<obj>)' or 'isinstance(<obj>, collections.abc.Callable)' to check if object is callable. When this cheatsheet uses '<function>' as an argument, it means '<callable>'. class Counter: def __init__(self...
