Emulating C++ namespaces with ChainMap and metaclass trickery

C++ namespaces are useful for encapsulating related objects within a single file, subdividing the global namespace without using classes. Python has modules, but they come in separate files. Using Python 3.3's ChainMap type, and some metaclass trickery, I abuse the class keyword to (almost) emu

Re: Experimental Python-based shell

I am open to suggestions and patches. I don't think the syntax strange, though: it offers a clear and distinct way to differentiate Python and shell commands, and shell commands can access Python variables when specified. And it is a simple rule, without footnotes needed. On Wed, Oct 3, 2012 at 11

Hi! I've got import scripts for a bunch of csv files into an sqlite database. I have one csv file per language. I don't write directly to the sqlite db; this is a django app and I'm creating items in my django models. My script (scripts, unfortunately) work just fine, but it feels beyond stupi

Re: Experimental Python-based shell

The chief benefit besides the searching, so far, is that you can use Py3k mixed with shell commands as the scripting language--so script in Python instead of bash. When using Python for scripting, Python lines are indented by an extra tab (or four spaces) while shell-like commands are not indented

Combinations of lists

Hi, I am looking for a clever way to compute all combinations of two lists. Look at this example: h = ['A','A','B','B'] m = ['a','b'] the resulting combinations should be of the same length as h and each element in m can be used twice. The sought after result using h and m from above is:
