Q:
Parsing a context-free grammar in Python
What tools are available in Python to assist in parsing a context-free grammar?
Of course it is possible to roll my own, but I am looking for a generic tool that can generate a parser for a given CFG.

"I warmly recommend PLY - it's a Lex/Yacc clone in Python that uses the language's introspection facilities in a sophisticated manner to allow for a very natural specification of the grammar. Yacc, if you recall, is the very embodiment of CFGs in an understandable DSL that defines how one parses them.\nI used it to... | [

Coloring close points

For simplicity assume that there are, say, 5 different colors to choose from. Turns out I've not the slightest idea how to... | Coloring close points | I have a dense set of points in the plane.

"If you can use whatever color you want, you can use that fact that colors are (almost) continuous. color the points according to their x,y coordinates, so you'll get as a side effect that close points will have a somewhat similar color.\nYou can use something like\npoint.color(R,G,B) = ( point.normalized_x, 0.5, 1... | [
