Perhapse there is a better way, but I solved so.
{{ Dump(self) }}

def Dump(self, aVal: bool = True) -> str:
    Res = []
    #pylint: disable-next=protected-access
    Vars = self._TemplateReference__context.parent
    for Key, Val in Vars.items():
        if (isinstance(Val, (str, int, float, dict, list))):
            Data = f'{Key} = {Val}' if aVal else f'{Key} = {type(Val).__name__}'
            print(Data)
            Res.append(Data)
    return '<br>\n'.join(Res)
