How to have an in-place string that updates on stdout

Question

I want to output to stdout and have the output \"overwrite\" the previous output.

For example; if I output On 1/10, I want the next output On 2/10

Answer 1

The solution for one string which will replace whole string

fmt.Printf("\033[2K\r%d", i)

For example, it correctly prints from 10 to 0:

for i:= 10; i>=0; i-- {
    fmt.Printf("\033[2K\r%d", i)
    time.Sleep(1 * time.Second)
}
fmt.Println()

which previous answers don't solve.
