symbol
— Constants used with Python parse trees¶
Source code: Lib/symbol.py
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 Grammar/Grammar
in the Python distribution for
the definitions of the names in the context of the language grammar. The
specific numeric values which the names map to may change between Python
versions.
Warning
The symbol module is deprecated and will be removed in future versions of Python.
This module also provides one additional data object:
-
symbol.
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.
