Go Language Learning Note 12: scope (range)

Rang this keyword is used primarily to iterate over arrays, slices, channels, or maps. Returns the index value in the array and the slice, returning key in the map.
This is particularly like Python's way. But it's a bit weird := to use segmentation instead of split in Python in . In Python, range is a function, not a keyword.

package mainimport "fmt"func main() {    nums := []int {10, 20, 30}    sum := 0        for i, num := range nums {        fmt.Println(i, num);        sum += num    }        fmt.Println("sum: ", sum);}
