[issue39760] ast.FormattedValue.format_spec unnecessarily wrapped in JoinedStr

[Serhiy Storchaka]

FYI you can use ast CLI:

$ echo 'f"is {x:d}"' | ./python -m ast
Module(
   body=[
      Expr(
         value=JoinedStr(
            values=[
               Constant(value='is ', kind=None),
               FormattedValue(
                  value=Name(id='x', ctx=Load()),
                  conversion=-1,
                  format_spec=JoinedStr(
                     values=[
                        Constant(value='d', kind=None)]))]))],
   type_ignores=[])
