Jun 8, 2018 · In case 2, we added async to the normal function. However the event loop will run it without interruption. Why? Because we didn't say where the loop is allowed to interrupt your function to run another task. In case 3, we told the event loop exactly where to interrupt the function to run another task. Where exactly? Right here! await asyncio ...

Sep 5, 2015 · For example, consider the function f(x, y) = x - y. If this function is called as z = f(3, 4) then the argument by the name of x will receive the value 3 and y will be 4, to return -1. If you reverse the arguments in the call, then you'd have x=4 and y=3 and it'd return 1 instead. The same is true of the arguments in the function you've provided.

% python -mtimeit -s'import test' 'test.foo()' 1000000 loops, best of 3: 0.254 usec per loop Do not try to use time.time or time.clock (naively) to compare the speed of functions. They can give misleading results. PS. Do not put print statements in a function you wish to time; otherwise the time measured will depend on the speed of the terminal.

The fact that you did callback(1, 2) first will call that function, thereby printing Sum = 3, and then main() gets called with the result of the callback function, which is printing the second line. Since callback returns no explicit value, it is returned as None. Thus, your code is equivalent to. callback(1, 2) main()

Jan 30, 2009 · Next we need a function to terminate the main() from the child thread: def quit_function(fn_name): # print to stderr, unbuffered in Python 2. print('{0} took too long'.format(fn_name), file=sys.stderr) sys.stderr.flush() # Python 3 stderr is likely buffered. thread.interrupt_main() # raises KeyboardInterrupt And here is the decorator itself:
