Golang统计文件中单词出现的频率

本文主要介绍通过golang实现读取文件，并对文件中出现的单次频率进行统计。

package main
 
import (
    "fmt"
    "io/ioutil"
    "log"
    "strings"
)
 
func main()  {
    buf,err := ioutil.ReadFile("test.txt")
    if err != nil {
        log.Fatal(err)
    }
    statisticTimes := make(map[string]int)
    wordsLength := strings.Fields(string(buf))
 
    for counts,word := range wordsLength {
                //判断key是否存在，这个word是字符串，这个counts是统计的word的次数。
        word,ok :=statisticTimes[word]  
        if ok{
            word = word 
            statisticTimes[wordsLength[counts]] = statisticTimes[wordsLength[counts]] + 1
        }else {
            statisticTimes[wordsLength[counts]] = 1
        }
    }
    for word,counts := range statisticTimes {
        fmt.Println(word,counts)
    }
}
