Lex and Yacc implementation for Python3


PLY is yet another implementation of lex and yacc for Python. Although several other parsing tools are available for Python, there are several reasons why you might want to take a look at PLY:
 * It's implemented entirely in Python.
 * It uses LR-parsing which is reasonably efficient and well suited
   for larger grammars.
 * PLY provides most of the standard lex/yacc features including
   support for empty productions, precedence rules, error recovery,
   and support for ambiguous grammars.
 * PLY is extremely easy to use and provides very extensive error
