字符串基本操作

package main

import (
    "fmt"
    "strings"
)

func main() {
    s := "hello world"
    //是否包含
    fmt.Println(strings.Contains(s, "hello"), strings.Contains(s, "?"))
    //索引
    fmt.Println(strings.Index(s, "o"))
    ss := "1#2#345"
    //分割字符串
    splitedStr := strings.Split(ss, "#")
    fmt.Println(splitedStr)
    //合并字符串
    fmt.Println(strings.Join(splitedStr, "#"))
    //是否包含前缀，后缀
    fmt.Println(strings.HasPrefix(s, "he"), strings.HasSuffix(s, "ld"))
}

输出：
