For a full list, see http://nedbatchelder.com/text/python-parsers.html For lex/yacc-like's, PLY, Spark, simpleparse, or ANTLR are probably the leaders. If you consider using pyparsing, then *don't* just try to do a straight transliteration from your existing lex/yacc implementation - you will end up fighting some of pyparsing's basic concepts. But if you already have this implemented and working in C, and given that parsing usually is such a performance-sucking operation, why not package the existing parser into a lib, and call it from python using ctypes, or some similar technology for embedding C code in Python? -- Paul -- http://mail.python.org/mailman/listinfo/python-list
