This is an ongoing list where I attempt to do the following: Play, Complete, and Rank every video game in the known universe in order to finally answer the age old question "What is the greatest game of all time?" For previous entries find the links on the attached spreadsheet. Watchdog is a handy Python package which uses the inotify Linux kernel subsystem to watch for any changes to the filesystem.What's the Greatest Video Game: Blazing Dragons This makes it an excellent foundation to build a a small script which takes action whenever a file is received in a directory, or any of the directory's contents change. An example might be a client-facing sftp server where you may want to receive an email when a file is received. asyncio.geteventloop ¶ Get the current event loop. I've included a shortened version of a watcher.py script I used for just such a purpose. If there is no current event loop set in the current OS thread, the OS thread is main, and seteventloop() has not yet been called, asyncio will create a new event loop and set it as the current one.
This tutorial will be specifically for Python 3.5+, using the latest asyncio keywords.

(event_handler, self.DIRECTORY_TO_WATCH, recursive=True) ASYNCIO FILE MONITOR CODEĪsyncio is the standard library package with Python that aims to help you write asynchronous code by giving you an easy way to write, execute, and structure your coroutines. project or source file by following the links above each example. # Take any action here when a file is first created. You may also want to check out all available functions/classes of the module asyncio. Print "Received created event - %s." % event.src_path The event loop is the core of every asyncio application. Start monitoring the fd file descriptor for read availability and invoke callback with the. Print "Received modified event - %s." % event.src_path # Taken any action here when a file is modified. To use this, just run python watcher.py from your console.
If you open any console window and upload a file or make any changes, you will see this printed out in your original console window.

Example of how to implement throttling in Asyncio/Aiohttp. To actually make this useful, you should wrap this up as a daemon or upstart script which can be run indefinitely. The order of this output is the heart of async IO. This gist consists of 4 files: throttler.py - Throttler class implementation asynciothrottlingexample.py - Throttling general coroutines aiohttpthrottlingexampleclient.py - Throttling aiohttp requests aiohttpthrottlingexampleserver.py - Web server for testing aiohttpthrottlingexampleclient. Talking to each of the calls to count() is a single event loop, or coordinator.
