删除切片中某一个元素

v1 := []int{1,2,3,4,5,6}
deleteIndex := 2
// 切片获取到 {1,2,4、5、6}
// 又获取到 [4，5，6}，将4、5、6要追加到
result := append(v1[:deleteIndex], v1[deleteIndex+1:]...);
fmt.Println(result) //{1,2,4,5,6}
fmt.Println(v1) //{1,2,4,5,6,6}

循环

v1 = []int{1,2,3,4,5,6}
for i:=0;i<len(v1);i++{
    fmt.Println(i, v1[i])
}
for index, value := range v1 {
    fmt.Println(index, value)
}
