Clicker Eats A Lot Of Processor Time - Python 3

I have a simple program that does the following: 1) User points a mouse somewhere, 2) then user presses Space, 3) and computer does certain amount of left-botton-mouse-clicks at

Solution 1:

Correct answer: I suspect a constant polling because of while True:. Insert sleep or pyautogui.PAUSE there (inside while loop, before if), if process sleeps for a while (even less then a second) it frees a lot of CPU cycles

Minor optimizations: Also you're initializing entire User32.dll in every loop... twice (because of or), it seems. And User32 is HUGE

Hints and notes:

If I remember python rules right, you just can move hllDll to a module level (above function defintion), get_space_state() will find it anyway. Or you can pass it as a parameter. And you don't need to redefine VK_SPACE every function call - though this is a micro-optimization

If all these fixes won't work, you should use debuggers, to find a true source of slowdowns

If you happen to have problems like this in the future, use something like Immunity or WinDbg to attach to process and see what's going on there
