Or Twisted and qt5-reactor.  While I believe Qt has some concurrent 
programming
features beyond just signals and slots, I don't think we get those in 
PyQt5.
Of course, correct me if I'm wrong.  So, Twisted lets you use deferreds 
and the
Python3.5+ (?) async etc keywords to write sequences without having to 
chain
signals and slots.
