我以一种基本的方式在一片结构中按小时对值进行平均,我会得到更好的方法来获得一个可以按小时、天、周等平均的最通用的函数。提前致谢致所有人。
package main
import (
"fmt"
"math/rand"
"time"
)
type Acc struct {
name string
money int
date time.Time
}
type Accs []Acc
const Tformat = "02/01/2006 15:04:05"
func main() {
var myaccs Accs
acc := 0
var loops int
var hour int
f1, _ := time.Parse(Tformat, "29/08/2013 00:00:19")
// Creating a Slice of structs
for i := 0; i < 10; i++ {
f1 = f1.Add(20 * time.Minute) //adding 20 minutes to every record
myaccs = append(myaccs, Acc{name: "christian", money: rand.Intn(200), date: f1})
fmt.Printf("Added to slice: %v, %d, %s\n", myaccs[i].name, myaccs[i].money, myaccs[i].date)
}
// Averaging
for _, v := range myaccs {
if acc == 0 {
hour = v.date.Hour()
acc += v.money
loops++
} else {
if v.date.Hour() == hour {
acc += v.money
loops++
} else {
fmt.Printf("Average money value to hour %d : %d\n", hour, acc / loops) //->Action
acc = v.money
hour = v.date.Hour()
loops = 1
}
}
//fmt.Println(v, acc, loops, hour)
}
fmt.Printf("Average money value to hour %d : %d\n", hour, acc / loops)//->Action
}
注意:Money 变量是一个 int,仅作为示例。
注 2:我正在考虑数据已经排序
