I agree. Enumerate is a direct, unequivocable verb that speaks directly to
the idea of sequentially assigning numbers to things.
Countoff is cool, but is a little colloquial. Also, any of the words
incorporating count (including itercount and countoff) have a subtle
implicit suggestion of counting from one rather than zero -- "firstly, let's
take item zero ..."
While indices have a clear meaning in Python, the old Dbase and SQL part of
me is a little bugged by index(), indexed(), indexer() since sequential
files are not at all like indexed files. When I index a database, sorting
takes place. When I index a collection, sequencing is applied. Much
As a part of speech, indexer() doesn't work as well in a sentence:
for linenum, line in indexer(file): ... # yuck!
Summary, I think we're down to subtle differences and have the following
