Making async for loops in Python

Question

The following code outputs as follows:

1 sec delay, print \"1\", 
1 sec delay, print \"2\", 
1 sec delay, print \"1\", 
1 sec delay, print \"2\"

Answer 1

With the aysncio library you can use aysncio.gather()

loop.run_until_complete(asyncio.gather(
  first(),
  second()
))

This can come in handy if you are also sending HTTP requests in parallel:

loop.run_until_complete(asyncio.gather(
  request1(),
  request2()
))
