Interesting things of 'getattr' and 'setattr'
I don't know it is a feature, or implement detail: class C(object): pass .... c = C() setattr(c, ' ', 3) getattr(c, ' ') 3 setattr(c, 'with blank', 4) getattr(c, 'with blank') 4 getattr / setattr seems treat any string as attribute name. ... 15 Dec 2009 08:56

multiprocessing callbacks?
Hey, everyone - I'm trying to use multiprocessing to create a process pool similar to multiprocessing.Pool, except that it works across multiple hosts.

Seek support for new slice syntax PEP.
Just as sets may now be written as {3,'hi'}, I propose that slices should be available using [start:end] syntax. Following example comes from projecteuler.net problem 166.

Dangerous behavior of list(generator)
In most cases, `list(generator)` works as expected. Thus, `list(<generator expression>)` is generally equivalent to `[<generator expression>]`. Here's a minimal case where this equivalence breaks, causing a serious and hard-to-detect bug in a program: def sit(): raise StopIteration() ... [f() f... 2 Jan 2010 16:05
