70The `ast` module helps Python applications to process trees of the Python
71abstract syntax grammar. The abstract syntax itself might change with
72each Python release; this module helps to find out programmatically what
73the current grammar looks like and allows modifications of it.
74
75An abstract syntax tree can be generated by passing `ast.PyCF_ONLY_AST` as
76a flag to the `compile()` builtin function or by using the `parse()`
77function from this module. The result will be a tree of objects whose
78classes all inherit from `ast.AST`.
79
80A modified abstract syntax tree can be compiled into a Python code object
81using the built-in `compile()` function.
82
83Additionally various helper functions are provided that make working with
84the trees simpler. The main intention of the helper functions and this
85module in general is to provide an easy to use interface for libraries
86that work tightly with the python syntax (template engines for example).

447 <p>Return a formatted dump of the tree in *node*. This is mainly useful
448 for debugging purposes. The returned string will show the names and the
449 values for fields. This makes the code impossible to evaluate, so if
450 evaluation is wanted *annotate_fields* must be set to False. Attributes
451 such as line numbers and column offsets are not dumped by default. If
452 this is wanted, *include_attributes* can be set to True.</p>

471 <p>When you compile a node tree with compile(), the compiler expects
472 lineno and col_offset attributes for every node that supports them. This
473 is rather tedious to fill in for generated nodes, so this helper adds
474 these attributes recursively where not already set, by setting them to
475 the values of the parent node. It works recursively starting at
476 *node*.</p>
