Please consider my comment. Firstly, it was in response to this comment:

> That's pretty unreadable for someone who doesn't know clojure.

The real reason for commenting was to show that it is readable and yes, providing the "readable" Python equivalent.

There are two points - firstly, Clojure is (or is becoming?) a lazy language and the list type is different, so no they are definitely not exactly the same.

This brings us to a broader point in that even if you were to have laziness in Python it still wouldn't matter because I'm not the only coder in the world and there are a lot of Pythonists like the author of the article who do it the Pythonic way, which as already hinted, I think is just braindead.

I will not argue the first point, but as for the second one: how does that one author determine what is 'the Pythonic way'? I think

  [sum(week) for week in partition(7, 7, daily)]

is 'the Pythonic way' and I find that quite a bit easier to comprehend than

  map(sum, partition(7, 7, daily))

The reason for that is as simple as it runs counter to what people usually preach: it is less concise. In the former, it is immediately clear that you are partitioning a list of days into partitions of weeks and summing over those weeks, resulting in a list of weekly sums. The extra word 'week', repeated twice, makes all the difference: all ingredients for comprehension are readily provided. The latter case, on the contrary, requires you to do a few mental operations to expand the expression into something meaningful, mentally adding the concept of a 'week' to understand what the code is doing. You need to do that everytime you read the code, which makes it less easy to understand.

> Just because you already happen to have a certain function at your disposal doesn't mean your language is suddenly superior.

You are certainly correct in that. That's not what makes Lisps superior to all other languages though, "it's the syntax stupid."

Edit: Sorry, I know that comment appears trollish (and it is), what I meant to say is that unlike Python, Lisp(s) have virtually no syntax, and are more powerful because they treat code as data. It would take me a blog post to explain why that's important, but if you give the language a shot you will see why that is (and compare how long it takes you to learn it to how long it took you to learn Python!).

Isn't there more to power than that? For example, in clojure you can't change the binding of a function in a namespace after it has been compiled. In python or ruby you do have the power to do that.

I'm not a Clojure expert, so I can't directly address that, but from the little that I know of Clojure though, I think you can do that by binding a function to a var, and then changing the binding of the var. (Can any Clojure experts exlaborate?)

Regardless, every Lisp that I am able to comment on (newLISP, elisp, Scheme, CL) can do that easily, so I doubt that Clojure would have difficulty with this.

It does have difficulty with this, check the mailing list. Just because something using s-expressions doesn't mean you can override functions in a namespace.

Thanks for that interesting thread! I do know though that newLISP can do this easily with a simple 'set' call.
