Question

有人请告诉我以下代码有什么问题吗？我是javascript的新手，我知道某处有一个丢失的逗号。谢谢。

i = 1:12
((i - 2) %% 12) + 1
[1] 12  1  2  3  4  5  6  7  8  9 10 11

Answer 1

bakeTime和bakeTemp都丢失了逗号。 mixInstructions函数也是如此，但它还没有必要。

Answer 2

您在bakeTime和bakeTemp之后缺少逗号，并且您的函数中遗漏了this " and bake at " + bakeTemp + " for " + bakeTime。

var cake = {
  firstIngredient: "milk",
  secondIngredient: "eggs",
  thirdIngredient: "cakemix",
  bakeTime: 22,
  bakeTemp: 420,
  mixingInstructions: function() {
    return "Add " +
    this.firstIngredient + " to " + this.secondIngredient + " and stir with " + this.thirdIngredient + " and bake at " + this.bakeTemp + " for " + this.bakeTime + " minutes.";
  }
};

console.log(cake.mixingInstructions())

Answer 3

对@Stephen L的跟进，

你忘了在import pandas as pd Data = pd.DataFrame({'L1': [1,2,3,4,5], 'L2': [6,7,3,5,6], 'ouptput':[10,11,12,13,14]}) Data

之后加上加号

Answer 4

返回“添加”

后，您也错过了“+”

Answer 5

您有以下3个错误：

之后缺少逗号烘烤时间：22 bakeTemp：420
在+

"Add"

this.中缺少bakeTemp而返回字符串中缺少bakeTime

return "Add " + this.firstIngredient + " to " + this.secondIngredient + " and stir with " + this.thirdIngredient + " and bake at " + this.bakeTemp + " for " + this.bakeTime + " minutes.";

＆＃13;

    var cake = {
      firstIngredient: "milk",
      secondIngredient: "eggs",
      thirdIngredient: "cakemix",
      bakeTime: 22,
      bakeTemp: 420,
      mixingInstructions: function() {
        return "Add "+ 
this.firstIngredient + " to " + this.secondIngredient + " and stir with " + this.thirdIngredient + " and bake at " + this.bakeTemp + " for " + this.bakeTime + " minutes.";
      }
    };
console.log(cake.mixingInstructions());
