[New-bugs-announce] [issue46073] ast.unparse produces: 'FunctionDef' object has no attribute 'lineno' for valid module

[Brian Carlson]

New submission from Brian Carlson <briancarlson6174 at gmail.com>:

Test file linked. When unparsing the output from ast.parse on a simple class, unparse throws an error: 'FunctionDef' object has no attribute 'lineno' for a valid class and valid AST. It fails when programmatically building the module AST as well.

It seems to be from this function: https://github.com/python/cpython/blob/1cbb88736c32ac30fd530371adf53fe7554be0a5/Lib/ast.py#L790
