array slicing and spaces around operators

  * Ignore the part of PEP-257 which says to put the trailing {{{"""}}} of a multi-line docstring on a separate line separated by a blank line.  (That rule appears to have been motivated by a limitation of Emacs which has been fixed.)
  * Ignore the part of PEP-8 which specifes 79- or 72- char line widths. We use 77 columns. In emacs set {{{fill-column}}} to 77 (e.g. {{{M-x set-variable fill-column 77}}}).
+ * PEP 8 says: "If operators with different priorities are used, consider adding whitespace around the operators with the lowest priority(ies)." This is a good rule; note that it also applies to some non-obvious low-priority operators, like '{{{:}}}' for list slicing. (Example: {{{a[b-c : d]}}} good, {{{a[b - c:d]}}} bad. If a slice is from the start or to the end of the array, put the '{{{:}}}' immediately next to the bracket on that side.)
