use of yield

Asked by nside

Hello,

I'm just curious: why do you use yield so often? For example in this statement (taken from testlib.py):
 client = yield onConn

Thanks!

Sorry for not having replied to this question earlier, I didn't set an answer contact in Launchpad and didn't notice you asked a question.

The reason for using yield is that tests use the inlineCallbacks idiom (http://twistedmatrix.com/documents/8.1.0/api/twisted.internet.defer.html#inlineCallbacks) which saves you from having to define a callback function and makes code look as if it were sequential.
