Turn a comma delmited string of ints into a slice of actual ints

Comma String to int string

package main

import "fmt"
import "strings"
import "strconv"

func main() {
	fmt.Println("Hello, playground")
	s := "1,2,4"
	n := commaStringToIntSlice(s)
	fmt.Println(n)
}	

func commaStringToIntSlice(cs string) []int{
    st := strings.Split(cs, ",")
    out := []int{}
    for i:=0; i< len(st); i++ {
	fmt.Println(st[i])
	val, err:= strconv.Atoi(st[i])
	if err == nil{
            out = append(out, val)
	}
    }
    return out
}
