the start time minus the stop time. This makes it time to call arbitrary functions regardless of location and keyword parameters.Note the following points:(1) The time module of Python agrees to access the current hour. Accuracy varies with each platform.On Windows, this call is known to achieve subtle precision. has been quite accurate.(2) The range call is placed outside the timing loop due to the.
