Adding values with reduce() function from the list of tuples

[perfringo]

Not great examples. I see why it was demoted from builtins and exiled to functools.

After built-in sum was added main value of reduce was... reduced :-).

From About Guido’s Article: “Fate of Reduce() in Python 3000”

Guido: “I value readability and usefulness for real code. There are some places where map() and filter() make sense, and for other places Python has list comprehensions. I ended up hating reduce() because it was almost exclusively used (a) to implement sum(), or (b) to write unreadable code. So we added built-in sum() at the same time we demoted reduce() from a built-in to something in functools (which is a dumping ground for stuff I don’t really care about :-).”
