python - Evaluation of 'not (False and True)' -

i came across example ("hacking secret ciphers python", p135) , i'm confused:

not (false , true) 

the example states evaluates false, fail see why. if parentheses modify precedence surely evaluating:

not (false) 

which evaluates true, doesn't it? or missing something?

// output functions configurable.  1 appends text  // pre element.  function outf(text) {    var mypre = document.getelementbyid("output");    mypre.innerhtml = mypre.innerhtml + text;  }    function builtinread(x) {    if (sk.builtinfiles === undefined || sk.builtinfiles["files"][x] === undefined)      throw "file not found: '" + x + "'";    return sk.builtinfiles["files"][x];  }    // here's need run python program in skulpt  // grab code textarea  // reference pre element output  // configure output function  // call sk.importmainwithbody()  function runit() {    var prog = document.getelementbyid("yourcode").value;    var mypre = document.getelementbyid("output");    mypre.innerhtml = '';    sk.pre = "output";    sk.configure({      output: outf,      read: builtinread    });    (sk.turtlegraphics || (sk.turtlegraphics = {})).target = 'mycanvas';    var mypromise = sk.misceval.asynctopromise(function() {      return sk.importmainwithbody("<stdin>", false, prog, true);    });    mypromise.then(function(mod) {        console.log('success');      },      function(err) {        console.log(err.tostring());      });  }

this covered in the errata:

page 135, interactive shell should this:

>>> not false , false # not false evaluates first  true  >>> not (false , false) # (false , false) evaluates first  false  

(thanks omer chohan)

it has been corrected in the online version of chapter, although not in pdf.
