Here is an example of such a problem I'm dealing with now: I'm
building large index of words in memory, it takes 50% o

Hi.
I'm using CPython 2.7 and Linux. In order to make parallel
computations on a large list of objects I want to use multiple
processes (by using multiprocessing module). In the first step I fill
the list with objects and then I fork() my worker processes that do
the job.
This should work optimall
Hello.
I found this strange behaviour of lambdas, closures and list
comprehensions:
>>> funs = [lambda: x for x in range(5)]
>>> [f() for f in funs]
[4, 4, 4, 4, 4]

Hi.
I would like to have declarative properties in Python, ie. something
like slots definitions in defclass in Common Lisp. It seems that even
Java will have it, using a library ( https://bean-properties.dev.java.net/

I know about 'property' function in Python, but it's normal usage
