go语言怎么遍历字符串

在Go语言中，可以使用range关键字来遍历字符串。下面是一个简单的例子：

package mainimport ("fmt")func main() {str := "Hello, World!"for index, char := range str {fmt.Printf("Character at index %d is %c\n", index, char)}}

在上面的例子中，我们使用range关键字遍历字符串str，并输出每个字符的索引和字符本身。输出结果为：

Character at index 0 is HCharacter at index 1 is eCharacter at index 2 is lCharacter at index 3 is lCharacter at index 4 is oCharacter at index 5 is ,Character at index 6 isCharacter at index 7 is WCharacter at index 8 is oCharacter at index 9 is rCharacter at index 10 is lCharacter at index 11 is dCharacter at index 12 is !
