报错：./main.go:24:36: syntax error: unexpected newline, expecting comma or }

原因在于结构体想要进行多行编写时，最后一个元素后面需要加上一个逗号

	p := Person{                                                                                                              
		Name: "Alex",                                                                                                         
		Age: "19",

	}    

报错：./main.go:26:12: err != t.Execute(os.Stdout, p) evaluated but not used

已评估但未使用，语句错误

	if err ：= t.Execute(os.Stdout, p); err != nil{                                                                            
		fmt.Println("There was an error: ", err.Error())
