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.
|
||
|
