[docs] [issue23495] The writer.writerows method should be documented as accepting any iterable (not only a list)

[Steven Barker]

Steven Barker added the comment:

Another Stack Overflow user pointed out that the DictWriter's writerows implementation (in pure Python) unnecessarily converts whatever its argument is into a list in memory before passing it on to the builtin writer.writerows method which would accept any iterable type. Probably it should be changed to use map or a generator expression instead.

So, perhaps this issue isn't purely documentation, but actually a small behavior enhancement as well.
