I would like to rewrite/amend it to work asynchronously with minimal effort such as:
def business_new(): content1 = fork open('big.file').read() # wraps up the calls into awaitables content2 = fork open('huge.file').read() # and put them into the event loop return content1 + content2 # variables are used => await evaluation
I might have missed something but I think you get my point.
No, you haven't missed anything, but I think the convenience APIs we're discussing in this thread are what you need, rather than async/await.
Specifically, your main application would remain synchronous, but the event loop could be used to run selected operations in a background thread:
def business_new(): future1 = asyncio.call_async(open('big.file').read) future2 = asyncio.call_async(open('huge.file').read) content1 = asyncio.wait_for_result(future1) content2 = asyncio.wait_for_result(future2) return content1 + content2
Cheers, Nick.
