|
|---|
| 11 |
|
|---|
| [2] | 12 | This module provides constants which represent the numeric values of internal
|
|---|
| 13 | nodes of the parse tree. Unlike most Python constants, these use lower-case
|
|---|
| 14 | names. Refer to the file :file:`Grammar/Grammar` in the Python distribution for
|
|---|
| 15 | the definitions of the names in the context of the language grammar. The
|
|---|
| 16 | specific numeric values which the names map to may change between Python
|
|---|
| 17 | versions.
|
|---|
| 18 |
|
|---|
| 19 | This module also provides one additional data object:
|
|---|
| 20 |
|
|---|
| 21 |
|
|---|
| 22 | .. data:: sym_name
|
|---|
| 23 |
|
|---|
| 24 | Dictionary mapping the numeric values of the constants defined in this module
|
|---|
| 25 | back to name strings, allowing more human-readable representation of parse trees
|
|---|
| 26 | to be generated.
