New submission from Aaron Meurer <asmeu...@gmail.com>:
This is tested in CPython master. The issue also occurs in older versions of
Python.
>>> ast.dump(ast.parse('f"{x}"'))
"Module(body=[Expr(value=JoinedStr(values=[FormattedValue(value=Name(id='x',
ctx=Load()), conversion=-1, format_spec=None)]))], type_ignores=[])"
>>> ast.dump(ast.parse('f"{x!r}"'))
"Module(body=[Expr(value=JoinedStr(values=[FormattedValue(value=Name(id='x',
ctx=Load()), conversion=114, format_spec=None)]))], type_ignores=[])"
>>> ast.parse('f"{x}"').body[0].value.values[0].value.col_offset
3
>>> ast.parse('f"{x!r}"').body[0].value.values[0].value.col_offset
1
The col_offset for the variable x should be 3 in both instances.
