3.16.5 AST Objects

Ordered and equality comparisons are supported between AST objects. Pickling of AST objects (using the `pickle` module) is also supported.

`ASTType`
  The type of the objects returned by `expr()`, `suite()` and `sequence2ast()`.

AST objects have the following methods:

`compile` ([filename])
  Same as `compileast(ast, filename)`.

`isexpr` ()
  Same as `isexpr(ast)`.

`issuite` ()
  Same as `issuite(ast)`.

`tolist` ([line_info])
  Same as `ast2list(ast, line_info)`.

`totuple` ([line_info])
  Same as `ast2tuple(ast, line_info)`.
