imperative mood in docstrings
pep 257 -- docstring conventions, as well as a myriad of books and other resources, recommend documenting a function's or method's effect as a command (do this, return that), not as a description (does this, returns that). what's the logic behind this recommendation? bagratte -- https://mail.python.org/mailman/listinfo/python-list

This can also be seen with a (monolingual) dictionary. For example: https://www.google.com/search?q=define+fly (that’s actually from the New Oxford American Dictionary): fly, verb: 1. move through the air under control. 2. move or be hurled quickly through the air. Those could be valid docstrings (if sheep could fly, of course…) — so, in other words, act as if you were writing a dictionary and not Python code. -- Chris “Kwpolska” Warrick http://kwpolska.tk PGP: 5EAAEA16 stop html mail | always bottom-post | only UTF-8 makes sense -- https://mail.python.org/mailman/listinfo/python-list

If it did, 'hell is frozen' would mean that one could say 'war is frozen', which makes no sense. No, I think this calls for a LISP-style predicate: if frozenp(hell): ChrisA -- https://mail.python.org/mailman/listinfo/python-list

Consider a class with a procedural method, that is, a method that does something: class Duck: def swim(self): Flap feet in a rhythmic manner so as to gracefully move through water. Here, we naturally write as if giving instructions to the duck, that is, using the imperative mood. Duck, swim. From there, it isn't a big step to using the same mood for functions: def count(haystack, needle): Return the number of needles in haystack. Here we are figuratively instructing the function, telling it what to do: Function, return the number of needles found in this haystack. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
