golang slice of strings code example

Example 1: 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 2: create slice golang

b := [2]string{"Penn", "Teller"}

Example 3: go slice

// loop over an array/a slice
for i, e := range a {
    // i is the index, e the element
}

// if you only need e:
for _, e := range a {
    // e is the element
}

// ...and if you only need the index
for i := range a {
}

// In Go pre-1.4, you'll get a compiler error if you're not using i and e.
// Go 1.4 introduced a variable-free form, so that you can do this
for range time.Tick(time.Second) {
    // do it once a sec
}
