Re: Move dictionary from instance to class level

To take things one step further, I would recommend using decorators to allow symbolic association of functions with the message identifiers, as follows: == (MESSAGE_ONE ,MESSAGE_TWO ,MESSAGE_THREE ) = xrange(3) class MyClass(object): method_dict = {}

Question about Multi-processing

AttributeError: 'module' object has no attribute 'f' But when I run this exact example in the command line interpreter it works fine : >>> p = Pool(5) >>> def f(x): ... return x*x ... >>> p.map(f,[1,2,3]) [3, 5, 7]

Interesting performance question

I have just noticed an oddity : Using python 3.6 building a tuple like this : my_tuple = tuple([x*x for x in range(1,1000)]) is about 1/3 quicker than     my_tuple = tuple(x*x for x in range(1,1000)) Measurements : $  python3 -m timeit 'my_tuple = tuple([x*x for x in range(1,1000)])' 1
