This demonstrates a task scheduling loop where tasks can send back other tasks to the queue.

Program input: a nested list of items that can either be integers, whose processing is simulated by waiting
a proportional amount of time, or another list, in which case after waiting a time proportional to its length,
sub-items are rescheduled for processing.

Solution is inspired by goroutines, channels and waitgroups.
Asyncio's Queue can serve both as channel and waitgroup, thanks to Queue.join() that blocks until the queue is empty.

Concurrent HTTP Requests with Python3 and asyncio

My friend who is a data scientist had wipped up a script that made lots (over 27K) of queries to the Google Places API. The problem was that it was synchronous and thus took over 2.5hours to complete.

Given that I'm currently attending Hacker School and get to spend all day working on any coding problems that interests me, I decided to go about trying to optimise it.

I'm new to Python so had to do a bit of groundwork first to determine which course of action was best.
