Description:

DParser is a simple but powerful tool for parsing, written by J. Plevyak.
DParser for Python gives Python programmers a seamless interface to DParser.

The features that set this Python parser apart from other Python parsers are:
+ it can deal with any grammar (GLR)
+ it is fast (based in C)
+ it does not require a compiler to operate.

DParser for Python also has many easy-to-use features found in other Python
parsers:
+ it does not require explicit definitions of tokens
+ it does not require a separate, non-Python grammar file
+ it uses function documentation strings to specify grammar rules
+ it does not output parser code that the user must compile or run.
