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.
