Some cool stuff with asyncio

What does asyncio.sleep(0) Do?

import asyncio 

class DummyAPI:
    async def get(self, number):
        print(f"GET {number} executed")
        await asyncio.sleep(number)
        return number, "a"
        
    async def context_switched_get(self):
        dispatch_list = []
        for i in range(1,6):
            dispatch_list.append(asyncio.ensure_future(self.get(i)))
            await asyncio.sleep(0)
        print("For context switched get, get is executed before this print statement")
        done = await asyncio.gather(*dispatch_list, return_exceptions=True)
        for e in done:
            print(e)
    
    async def gathered_get(self):
        dispatch_list = []
        for i in range(1,6):
            dispatch_list.append(asyncio.ensure_future(self.get(i)))
        print("For regular gathered get, get is executed after this print statement")
        done = await asyncio.gather(*dispatch_list, return_exceptions=True)
        for e in done:
            print(e)

    
    async def main(self):
        await self.context_switched_get()
        await self.gathered_get()

dummy = DummyAPI()
loop = asyncio.get_event_loop()
loop.run_until_complete(dummy.main())
