Question

我正在尝试将javascript代码翻译成python，我遇到的问题是我不知道某些表达式是做什么所以现在我卡住了。这是我想要翻译的代码。

    var generateID = function(dob, male, citizen) {
        var gender = getRandom(5) + (male ? 5 : 0);//this line if anyone knows what it does
        var citBit = +!citizen;//this is the line that i need to translate to a python equivalent
    };

Answer 1

它将转换为布尔值

＆＃13;

getRandom = function(s) { return s }

var generateID = function(dob, male, citizen) {
        var gender = getRandom(5) + (male ? 5 : 0);//this line if anyone knows what it does
        var citBit = +!citizen;//this is the line that i need to translate to a python equivalent
        console.log(citBit);
    };
    
generateID(null , 'yes', 1)

＆＃13;

Answer 2

+! will test return opposite boolean representation for your input. 

if your input is `true` will return false. 
if it is `false` will return `true`

例如：

您的给定输入为> 0，其布尔表示为1，因此它将!并返回false等效0。同样，如果其0将返回1

Answer 3

如果值为true，则返回false;如果值为false，则返回true

这些Javascript表达式（+！）做什么？
