cProfile output read

[tech3371]

python-version 3.6.8 Like we discussed in office hour today, I wrote cProfile to get the time it takes to run function call and it's good. original code:

        #start the cProfile timer here
        prof.enable()
        ret = benchmarkFunction(x,lambda x: 2*x,timestep) #function that does the calculation
        prof.disable()
        s      = io.StringIO()
        sortby = 'time'
        ps     = pstats.Stats(prof, stream=s).sort_stats(sortby)
        ps.print_stats(10)
        print(s.getvalue())

I got Output like below:

14809 function calls in 0.054 seconds

And I need to get the tottime from this line:

 21    0.018    0.001    0.054    0.003 <ipython-input-101-80a6d7e4cb13>:3(benchmarkFunction) 

How can I do that?

Look at ps.stats, which is a dict containing this information.
