The example on this page: http://docs.python.org/2/library/profile.html?highlight=pstats#profile.Profile Shows: import cProfile, pstats, io pr = cProfile.Profile() pr.enable() ... do something ... pr.disable() s = io.StringIO() ps = pstats.Stats(pr, stream=s) ps.print_results() Where "ps.print_results()" should be "ps.print_stats()"

Thanks for the patches, however the Python 2 example doesn't work. I think a BytesIO should be used instead of a StringIO, and print_stats() only returns a pstats.Stats instance, without actually printing any result. I wonder if print_results was an old method that has been removed and if now there's another way to print the results. I haven't tried on Python 3 yet, but the same comment might apply there too.

A slightly more complete example that I tested: http://stackoverflow.com/a/16077568/1556290

Here is a fixed version for python2.7. Using StringIO instead of io module fixes the problem pointed by Ezio. The print_stats method dumps the stats either on sys.stdout if `Stats` class is declared without a stream specification or in the given stream parameter (the name print_stats may be a bit misleading).
