这个函数主要统计字母个数、数字个数、汉字和其他字符的个数（注意汉字和其他字符一起统计）

GO语言的代码有

func main() {   searchCount("Golang python")   searchCount("我哼着" + "12345,54321" + "不小心踩了一坨屎，It smells good")}func searchCount(src string) {   letters := "abcdefghijklmnopqrstuvwxyz"   letters = letters + strings.ToUpper(letters)   nums := "0123456789"   numCount := 0   letterCount := 0   othersCount := 0   for _, i := range src {      switch {      case strings.ContainsRune(letters, i) == true:         letterCount += 1      case strings.ContainsRune(nums, i) == true:         numCount += 1      default:         othersCount += 1      }   }   fmt.Println(letterCount, numCount, othersCount)}

python代码简洁了一点

def  searchCount(src):    numCount=0    letterCount=0    otherCount=0    for i in src:        if  i.isdigit():            numCount+=1        elif i.isalpha():             letterCount+=1        else:            otherCount+=1    print(letterCount,numCount,otherCount)searchCount("Golang python")a="我哼着" + "12345,54321" + "不小心踩了一坨屎，It smells good"searchCount(a)
