[Numpy-discussion] Profiling line-by-line

[David G. <dav...@gm...>]

Is there any way to do line-by-line profiling in Python? The profiling
results can tell me how much time is spent in all functions, but within a
given function I can't get any idea of how much time was spent on each line.
For example, in the example below, I can see that graphWidth.py is taking
all the time, but there are many lines of code in graphWidth.py that aren't
function calls, and I have no way of knowing which lines are the
bottlenecks. I'm using hotspot currently, by the way.

   ncalls  tottime  percall  cumtime  percall filename:lineno(function)
        1    0.215    0.215    0.221    0.221 graphWidth.py:6(graphWidth)
       27    0.001    0.000    0.003    0.000 oldnumeric.py:472(all)
       26    0.002    0.000    0.002    0.000 oldnumeric.py:410(sum)
       26    0.001    0.000    0.002    0.000 oldnumeric.py:163(_wrapit)
       26    0.001    0.000    0.001    0.000 oldnumeric.py:283(argmin)
       26    0.000    0.000    0.000    0.000 numeric.py:111(asarray)
        0    0.000             0.000          profile:0(profiler)
