typed_ast
is a Python 3 package that provides a Python 2.7 and Python 3
parser similar to the standard ast
library. Unlike ast
below Python 3.8,
the parsers in
typed_ast
include PEP 484 type comments and are independent of the version of
Python under which they are run. The typed_ast
parsers produce the standard
Python AST (plus type comments), and are both fast and correct, as they are
based on the CPython 2.7 and 3.7 parsers.
Note: The ast
module of Python 3.8+ supports all features of typed_ast
.
typed_ast
does not support parsing code that uses syntax introduced in
Python 3.8 onwards.
We recommend using ast
on Python 3.8 or above.
