A table with these columns might be helpful for performance comparisons: [ structure, operation, big_o, keyset, # signed ints, randstrs timeit_output, system_load, architecture, # x86_84, aarch64 os, ]
Does anyone have a recommendation for a tool that stores such benchmark data in JSON and merges the e.g. per-arch output? Are there URIs for Big-O notation that could be added as e.g. structured attributes in docstrings or annotations? I just added a ._repr_html_() method to the tabulate package so that, in addition to the many excellent ASCII formats tabulate prints, tabulate.tabulate(data, tablefmt='html') displays an html-escaped table in Jupyter notebooks? It's not yet released, so you'd need to `pip install -e git+ https://github.com/astanin/python-tabulate@master#egg=tabulate` On Tue, Dec 24, 2019, 3:53 AM Larry Hastings <la...@hastings.org> wrote: > > On 12/23/19 8:09 PM, Kyle Stanley wrote: > > > Chris Angelico wrote: > > I think this is an artifact of Python not having an empty set literal. > > [snip] > > When both use the constructor call or both use a literal, the > > difference is far smaller.
