[issue32172] Add length counter for iterables

[Steven D'Aprano]

Steven D'Aprano <steve+python at pearwood.info> added the comment:

Not every trivial one-liner needs to be in the standard library. In this case, there are two easy (and obvious) ways to do it:

sum(1 for x in iterator)

len(list(iterator))

(The first probably saves memory; the second probably is faster.)

Given how rare it is to care ONLY about the length of an iterator, I see no reason why this needs to be in the std lib. If you disagree, please take it to the Python-Ideas mailing list to get community support first before re-opening this ticket.
