问题
I am looking for some thing like time.sleep in Kivy, because kivy does not support time.sleep and it hangs when i run a program using time.sleep.
I searched and found a function called:
Clock.schedule_interval(self.callback, interval)
but its not probably like time.sleep. Clock.schedule calls a function every x seconds, but I want to make a delay.
kivy.clock

Kivy supports time.sleep just fine, it just doesn't do what you want it to do - as per the function name, it sleeps, which means kivy 'freezes' as it isn't taking input, updating the graphics etc.
Anyway, it sounds like you want Clock.schedule_once(function, time). That will call the function (with a default argument dt) in time seconds.
