golang 终端中怎样只在一行中实时更新打印内容

平时在终端中安装软件,有些软件能在某个位置中实时更新打印进度,在golang的终端输出中,怎样实现?

比如我要在终端中打印一个进度:

fmt.Print("进度:")
fmt.Printf("%d%%",25)
fmt.Printf("%d%%",50)
fmt.Printf("%d%%",75)
fmt.Printf("%d%%",100)

这么使用的话效果是:

进度:25%50%75%100%

我想要的效果是在进度:后面实时更新打印数据,golang中怎样实现?

这个是通过 printf("进度:%d%% ", i) 实现的。试试看
