go语言删除切片的方法：首先创建一个go示例文件；然后声明变量；最后通过“ss=append(ss[:index],ss[index+1:]...)print("after delete",ss)”方式删除切片元素即可。
本教程操作环境：Windows7系统、Go1.14版，Dell G3电脑。
1.声明变量，go自动初始化为nil，长度：0，地址：0，nil
func main(){
var ss []string;
fmt.Printf("length:%v \taddr:%p \tisnil:%v",len(ss),ss, ss==nil)
}
---
Running...
length:0 addr:0x0 isnil:true
Success: process exited with code 0.2.切片的追加，删除，插入操作
func main(){
var ss []string;
fmt.Printf("[ local print ]\t:\t length:%v\taddr:%p\tisnil:%v\n",len(ss),ss, ss==nil)
print("func print",ss)
//切片尾部追加元素append elemnt
for i:=0;i<10;i++{
ss=append(ss,fmt.Sprintf("s%d",i));
}
fmt.Printf("[ local print ]\t:\tlength:%v\taddr:%p\tisnil:%v\n",len(ss),ss, ss==nil)
print("after append",ss)
//删除切片元素remove element at index
index:=5;
ss=append(ss[:index],ss[index+1:]...)
print("after delete",ss)
//在切片中间插入元素insert element at index;
//注意：保存后部剩余元素，必须新建一个临时切片
rear:=append([]string{},ss[index:]...)
ss=append(ss[0:index],"inserted")
ss=append(ss,rear...)
print("after insert",ss)
}
func print(msg string,ss []string){
fmt.Printf("[ %20s ]\t:\tlength:%v\taddr:%p\tisnil:%v\tcontent:%v",msg,len(ss),ss, ss==nil,ss)
fmt.Println()
}
