time.sleep(5) will make entire program to sleep?

Question

In my program, i have to wait for some installations to complete. The following is the pseudo Code for the same:

    Clock.schedule_once(self.instantiate_module1,2)
    Clock.schedule_once(self.instantiate_module2,2)
    while (instantiation is not done)
          time.sleep(4)

    Continue Execution
But the installations are never done.

Here sleep will keep the entire program(if we have multiple threads) to pause/sleep? How sleep method works?

Answer 1

time.sleep is blocking the main thread, where the clock also runs. A simple solution is to just clock schedule your checking function every four seconds instead, and cancel it when the installation finishes.
