alternative to creating and executing simple grammars - Python 3.x
The parsing module is an alternative approach to creating and executing simple grammars, vs. the traditional lex/yacc approach, or the use of regular expressions. The parsing module provides a library of classes that client code uses to construct the grammar directly in Python code.
Here's an example:
from pyparsing import Word, alphas greet = Word(alphas) + "," + Word(alphas) + "!" hello = "Hello, World!" print hello, "->", greet.parseString(hello)
This package contains the Python 3.x version of python-pyparsing.
