如何从切片中分离数字？

Question

Let's say I have a list with 10 numbers: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I would like my program to slice every 3 numbers, for example:

[1,2,3]
[4,5,6]
[7,8,9]

How can I do it? Grateful

Answer 1

For example, with n = 3,

package main

import "fmt"

func main() {
    list := []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
    for a, n := list, 3; len(a) >= n; a = a[n:] {
        slice := a[:n]
        fmt.Println(slice)
    }
}

Output:

[1 2 3]
[4 5 6]
[7 8 9]
