# Computational Stopwatch Simple stopwatch to easily print the elapsed time of a set of operations. It's a minimalistic library, but it is very useful in many real cases. ## Usage The easiest way to use this tool is in conjunction with the **with** python statement: ```python >> from computational_stopwatch import Stopwatch >> >> with Stopwatch(): >> time.sleep(3) # <- simulates a computation Elapsed time 0:00:03.003106 ``` Anything within the scope of the **with** statement will count against the elapsed time. An optional task name to be printed along the elapsed time (e.g. for better identification in a log) can be set in the constructor. This name will be prepended to the printed message. This is useful to track the elapsed time of several tasks ran in sequence. ```python >> with Stopwatch("My short task"): >> time.sleep(3) # <- simulates a computation My short task complete. Elapsed time 0:00:03.003106 ``` Alternatively to the use with the **with** statment, the class can be directly instantiated and the print function explicitly called. ```python >> sw = Stopwatch() >> time.sleep(3) >> sw.print_elapsed_time() Elapsed time 0:00:03.003280 ``` or simply ```python >> sw = Stopwatch() >> time.sleep(3) >> print(sw) 0:00:03.003269 ``` The start time can be reset with the **reset_time** function and the **get_elapsed_time** method returns the unformatted elapsed time, which is useful for numerical comparisons. Different **verbosity** levels can be set in the constructor, with 2 as the default level, with 1 only the time is printed when the object is deleted, and with 0 nothing is printed. This is convenient to directly assess the elapsed time in seconds without any rogue prints on deletion: ```python >> sw = Stopwatch(verbosity=0) >> time.sleep(3) >> t = sw.get_elapsed_time() >> print(t) 3.0032315254211426 ``` By default, everything is printed on the standard output. Further or alternative streams can be set in the constructor. For instance, the folowing snipped: ```python >> log_file = open('/tmp/my_log_file.txt','w') >> with Stopwatch("My logged task", streams=[sys.stdout, log_file]): >> time.sleep(3) # <- simulates a computation My logged task complete. Elapsed time 0:00:03.002731 ``` prints the message both on the standard output as well as in the log file for future perusal. # Versions History ## v1.0.3 - added ```__str__ ``` function to easily include just the time stamp inside other strings ## v1.0.2 - updated the README - added multiple streams functionality ## v1.0.1 - minor fixes ## v1.0.0 - first reelease
