Here is a simple class to make reporting start, finish and elapsed time easy. If you are running python scripts at command line, this utility will make it easier to keep track of the progress of your processing.
Here is an example of usage:
from arcpyh import DateTimer import time timer = DateTimer() timer.start() time.sleep(10) timer.stop()
Here is an example of the output:
Started: 2012-01-23 14:50:00 Finished: 2012-01-23 14:50:10 (Elapsed: 0:00:10)
Here is the important code. Save this in a file called “arcpyh.py” and put it in the same directory of the script you are running or elsewhere in your pythonpath.
from datetime import datetime class DateTimer: ''' Handy timer that reports start time, end time and delta time report:(default=True) If True, prints automatically Example output: Started: 2012-01-23 14:40:37 Finished: 2012-01-23 14:40:47 (Elapsed: 0:00:10) ''' NO_START_MSG = "Timer was never started."
