Opening network connections ¶ coroutine loop. Return a task factory or None if the default one is in use. Must return a asyncio.Future-compatible object. (loop, coro, context=None), where loop is a reference to the activeĮvent loop, and coro is a coroutine object. Otherwise, factory must be a callable with the signature matching If factory is None the default task factory will be set. The current context is used when no context is provided.Ĭhanged in version 3.11: Added the context parameter. If you want the callback to be called with keywordĪn optional keyword-only context argument allows specifying aĬustom contextvars.Context for the callback to run in. The optional positional args will be passed to the callback when Scheduled for exactly the same time, the order in which they Number of seconds (can be either an int or a float).Īn instance of asyncio.TimerHandle is returned which canĬallback will be called exactly once. Schedule callback to be called after the given delay call_later ( delay, callback, * args, context = None ) ¶ Event loop uses monotonicĬlocks to track time. To be called at some point in the future. Using partial objects is usually more convenient than using lambdas,Īs asyncio can render partial objects better in debug and errorĮvent loop provides mechanisms to schedule callback functions partial ( print, "Hello", flush = True )) # will schedule "print("Hello", flush=True)" loop. Note that there is no need to call this function when This should be used to reliably finalize all scheduled #PSYCHOPY GET LOOP NUMBER GENERATOR#The event loop will issue a warning if a new asynchronous generator Schedule all currently open asynchronous generator objects toĬlose with an aclose() call. Should be called after the event loop is closed. This method is idempotent and irreversible. This method clears all queues and shuts down the executor, but does The loop must not be running when this function is called. Return True if the event loop was closed. Return True if the event loop is currently running. Note that new callbacks scheduled by callbacks will not run in thisĬase instead, they will run the next time run_forever() or The loop will run the current batch of callbacks and then exit. If stop() is called while run_forever() is running, Those that were already scheduled), and then exit. Run all callbacks scheduled in response to I/O events (and The loop will poll the I/O selector once with a timeout of zero, If stop() is called before run_forever() is called, Run the event loop until stop() is called. Return the Future’s result or raise its exception. Is implicitly scheduled to run as a asyncio.Task.

Set loop as a current event loop for the current OS thread. In future Python releases, this function will be an alias of Deprecated since version 3.10: Deprecation warning is emitted if there is no running event loop.
