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：
