    The standard output for cProfile when run from a command line is not very useful. It has two main flaws:

    • Default sort order is by name of function
    • It strips the full path of source files

    The first makes it very hard to look at the output. The second is very annoying when you get a bunch of __init__.py in the output.

    Suggested solution:

    • Default cumulative time sort order
    • Show one additional folder level when filename is __main__ or __init__

    Can you paste a sample output showing how it looks like pre and post patch?

    There is an example output on github. Should I paste it here too? I can do it once I get home if you want.

    The sorting is easy to see, but the other change is that this line:

      100    0.000    0.000    0.001    0.000 __init__.py:183(dumps)

    ...now looks like this:

      100    0.000    0.000    0.001    0.000 json/__init__.py:183(dumps)

    I have resubmitted the patch that changes the default sorting order in #31929 as it was asked to separate that from the original patch by Anders.

    I also added documentation changes that follow from changing the default sorting order.
