I am trying to reuse the code shown in the following SO post answer:
Especially the part that does:
async with sema, session.get(url) as response:
response = await response.read()
But I don't understand it.. how can 2 "contexts" (sema and session.get(url)) be combined into 1 variable?
Can anyone give me a quick explanation of that syntax?
Value from sema
's __aenter__
method is simply threw away and not assigned to any local variable.
Below is an equivalent for non-async code:
with ctx1, open(file) as fh:
content = fh.read()
