| |
| This module provides constants which represent the numeric values of |
| internal nodes of the parse tree. Unlike most Python constants, these |
| use lower-case names. Refer to the file \file{Grammar/Grammar} in the |
| Python distribution for the defintions of the names in the context of |
| the language grammar. The specific numeric values which the names map |
| to may change between Python versions. |
| |
| This module also provides one additional data object: |
| |
| \setindexsubitem{(in module symbol)} |
| |
| |
| \begin{datadesc}{sym_name} |
| Dictionary mapping the numeric values of the constants defined in this |
| module back to name strings, allowing more human-readable |
| representation of parse trees to be generated. |
| \end{datadesc} |
