Hi folks, Just a suggestion for a documentation tweak. Currently the docs for len() on a set say this: .. describe:: len(s) Return the cardinality of set *s*. I'm a relatively seasoned programmer, but I don't really have a maths background, and I didn't know what "cardinality" meant. I could kind of grok it by context, but could we change this to something like the following? .. describe:: len(s) Return the number of elements in set *s* (cardinality of *s*). Happy to open a bugs.python.org issue on this, but wanted to get general consensus first. -Ben
@Ben I am not either a great fan of formal (mathematic) definitions (: Lorenzo Moriondo, from mobile ~~it.linkedin.com~in~lorenzomoriondo~~ On Feb 8, 2016 5:38 PM, "Ethan Furman" <ethan@stoneleaf.us> wrote:

Return the number of elements (cardinality) of *s*.
+1
+1 to this for me as well

Agreed. Done. :) -gps
