How accurate is python's time.sleep()?

Question

I can give it floating point numbers, such as

time.sleep(0.5)

but how accurate is it? If i give it

time.sleep(0.05)
         


        

Answer 1

def test():
    then = time.time()  # get time at the moment
    x = 0
    while time.time() <= then+1:  # stop looping after 1 second
        x += 1
        time.sleep(0.001)  # sleep for 1 ms
    print(x)

On windows 7 / Python 3.8 returned 1000 for me, even if i set the sleep value to 0.0005

so a perfect 1ms
