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))
