How to iterate over string characters in Go

To iterate over the characters in a string, a for..range loop may be utilised.

package main

import "fmt"

func main() {
	str := "I ♥ Go!"
	for _, ch := range str {
		fmt.Println(ch)
	}
}

This outputs the Unicode code point for each character in the string:

73
32
9829
32
71
111
33

If you need to access the characters represented by the Unicode code point, you can use the %c fmt verb with fmt.Printf or fmt.Sprintf:

package main

import "fmt"

func main() {
	str := "I ♥ Go!"
	for _, ch := range str {
		fmt.Printf("%c\n", ch)
	}
}
