This article illustrates the use of range in the go language. Share with you for your reference. The specific analysis is as follows:

range is a function defined by the go language system.

The function iterates through each value in an array, returning the lower value of the value and the actual value here.
If a[0]=10, then the return value of a[0] is 0, 10.

Here is an example: this example is the average value of an array.

package main
import (
func main() {
    sum := 0.0
    var avg float64
    xs := []float64{1, 2, 3, 4, 5, 6}
    switch len(xs) {
    case 0:
        avg = 0
        for _, v := range xs {// The underscore indicates that the value is left out, that is, the subscript index is left out
            sum += v
        avg = sum / float64(len(xs))

I hope this article has been helpful to your programming of Go language.
