Interrupt Sleep function

Expand Post »
Is there a way one can interrupt the sleep() function with a key press in Python?

Re: Interrupt Sleep function

Look at KeyboardInterrupt in the Python reference. Right now, I don't have a good example. I try to work on one!

Re: Interrupt Sleep function

So far I have only found one function that will work during the active sleep() ...
Python Syntax (Toggle Plain Text)
  1. import time
  2. import msvcrt
  3. time.sleep(10)
  4. # prints the key value during sleep
  5. if msvcrt.kbhit():
  6. print msvcrt.getch()
Edit:
Ouch! The IDE fooled me! This does not make sense, forget it! Sorry!

Re: Interrupt Sleep function

If it's anything like the sleep(t) function I have been using with C++, there is no way to stop it early. Maybe ctrl/alt/del, but that is not what you want to normally do.

Re: Interrupt Sleep function

havn't got an example, but my very rough guess is maybe you could do something along the lines of;

wrap a function around the time.sleep() function that when called it starts the sleep in another thread so that the program will only continue untill;
sleep ends,
thread gets killed (stoppped)
so the way to interrupt could be to manually shut down the thread which in turn would shut down the sleep

OR

you could make your own sleep class that allows you to kill it?

something along those lines anyway

Re: Interrupt Sleep function

Thanks a1eio,
I just remembered hanging an old Delphi snippet on the DaniWeb code snippet laundry line a long time ago, that talked about the very same thing that Ene brought up.
