strings.split golang example
Example 1: golang string split
s := strings.Split("a,b,c", ",")
Example 2: golang slice string
First of all, you should really read about strings, bytes and runes in Go.
And here is how you can achieve what you want: Go playground (I was not able to properly paste arabic symbols, but if Chinese works, arabic should work too).
s := "abcdefghijklmnop"
fmt.Println(s[2:9])
s = "something which is display"
fmt.Println(string([]rune(s)[2:9]))
Example 3: golang split spaces
someString := "one two three four "
words := strings.Fields(someString)
fmt.Println(words, len(words)) // [one two three four] 4
