Python: high precision time.sleep

Question

can you tell me how can I get a high precision sleep-function in Python2.6 on Win32 and on Linux?

Answer 1

You can use floating-point numbers in sleep():

The argument may be a floating point number to indicate a more precise sleep time.

So

time.sleep(0.5)

will sleep for half a second.

In practice, however, it's unlikely that you will get much more than millisecond precision with sleep because operating systems usually only support millisecond sleeps and because very short amounts of time quickly get unreliable.
