Question

import UIKit

var str = "Hello, playground"  
let NumberofStopLights: Int = 4 
var population: Int 
population = 5000 
let TownName = "HappyPlace"
let TownDescription = return "/(TownName) has a population of /(population) and /(numberofStopLights) Stop Lights 
print (TownDescription)

我希望整数自动进入/（TownName），/（population）和/（numberStopLights）空格，尝试使用return函数，但它不起作用。所以......我试着根据Stack Overflow上的另一篇文章做了这个，它说要把它放在它面前，但那不起作用，所以...下一步是什么？（上面的代码）

Answer 1

你不需要返回，你的插值也是错误的。应该是\（）而不是/（）而你忘记了最后一个“在声明你的Townname字符串时。

var str = "Hello, playground"
let NumberofStopLights: Int = 4
var population: Int
population = 5000
let TownName = "HappyPlace"
let TownDescription = "\(TownName) has a population of \(population) and \(NumberofStopLights) Stop Lights"
print (TownDescription)

你也应该尝试使用大写和小写的正确方法，虽然编译器并不关心，但它最终会让你的生活变得更轻松！

返回函数不工作尝试将整数转换为字符串时
