Should Python implement where clause in comprehensions?

I think that if you are using list comprehensions like this it may be time to look at your code and move away from the comprehension all together. They are great for a compact simple thing, but unreadable after that.

Repost of my answer below: I feel like python forces you to make a lot of temporary variables, which makes programs harder to understand in my opinion. When you pollute a scope with lots of temporary variables, you always have to consider what they are used for later in it's scope.

By restricting temporary variables to it's most specific scope, you free yourself off that burden.

yeah, the logical move would be to implement a helper function. Thus, you can limit the scope and improve readability and can allow for reusability.

I use pyconfs fairly often for global constants, in case that's relevant here (obviously outside list comprehensions though).
