I love writing python, but the lack of decent map/reduce/etc. (that are really good in Javascript - the other language I mainly write) hurts. Stuff like your example really feels burdensome and inelegant in comparison.

Python list comprehensions _are_ map/reduce.

I think you mean map/filter.

Yes, thanks for correcting me.

Sure, but they compose really bad.

Why? Just assign to a variable, then do another list comprehension on the next line, no?

And that is a pretty sad state of affairs compared to ways that do compose well, like the one in Ruby which you can easily chain.
