I just counted the number of reduce I used in my current python project (6k lines). reduce comes up 32 times. And by comparison, map is used 159 times and filter 125 times - for some reason I tend to use list comprehensions less than I should.

I also thing you use map not a ton if you get the list comprehension syntax down... it is a map with less cruft mostly...

curious how often reduce is used with something else than operator.add?

One occurence was to calculate the GCD of a list of polynomials.

In fact I had "reduce" appearing in the names of some of my variables so I used it less than 32 times, about 20 times in that project.

I see nothing particularly inspiring in the examples posted on http://stackoverflow.com/questions/15995/useful-code-which-u...

Could you show your reduce calls?

They are very similar to this one from your link: http://stackoverflow.com/questions/15995/useful-code-which-u...
