If you have the patience to wait until the script finishes, then you can see it works in single-threaded mode due to the GIL. As if this weren’t enough proof, the message on the screen confirms that you’re indeed running pure Python code. Now it’s time to compile your extension ...
Rather than having all of your code wait until thetime.sleep()function finishes, you can execute the delayed or scheduled code in a separate thread using Python’sthreadingmodule. The separate thread will pause for thetime.sleepcalls. Meanwhile, your program can do other work in the original ...
pygame.init() FPSCLOCK = pygame.time.Clock() # Because the Surface object stored in DISPLAYSURF was returned # from the pygame.display.set_mode() function, this is the # Surface object that is drawn to the actual computer screen # when pygame.display.update() is called. DISPLAYSURF = p...
If you wanted to apply the second approach to the countdown example code, then you could define a new function usingprint()as a partial and call itunbuffered_print(). Then you could use it instead of the built-inprint()where you want unbuffered output: ...
When id was called, Python created a WTF class object and passed it to the id function. The id function takes its id (its memory location), and throws away the object. The object is destroyed. When we do this twice in succession, Python allocates the same memory location to this ...
If one task blocks for a while on I/O, all of the other tasks have to wait until it finishes and they are executed in turn. This definite order and serial processing are easy to reason about, but the program is unnecessarily slow if the tasks don't depend on each other, yet still ...

Runs the requested state and waits until it finishes. Example: run_state(odrv0.axis0, AxisState.MOTOR_CALIBRATION) Upon entering, all pending errors are cleared (clear_errors()). After entering the requested axis state, the function continuously polls the state and feeds the watchdog at 5...
