| 1 | # This file describes the nodes of the AST in ast.py. The module is

| 2 | # generated by astgen.py.
|

| 3 | # The descriptions use the following special notation to describe
|
|---|
| 4 | # properties of the children:
|
|---|
| 5 | # * this child is not a node
|
|---|
| 6 | # ! this child is a sequence that contains nodes in it
|
|---|
| 7 | # & this child may be set to None
|
|---|
| 8 | # = ... a default value for the node constructor (optional args)
|
|---|
| 9 | #
|
|---|
| 10 | # If you add node types here, please be sure to update the list of
|
|---|
| 11 | # Node types in Doc/lib/asttable.tex.
