Sum of values in a map using Golang

Question

If I have a map in Golang like: m = {"p1":2.4, "p2":1.5, "p3":1.7}

Now want to obtain the sum of just the values in map m. How is this done? I know to loop through an array to get the sum: array = [2.4, 1.5, 1.7]
sum := 0
for i := 0; i <= len(array); i++{
sum += i
fmt.Println(sum)

How do I write this for a map using Golang?

Answer 1

var sum float32 = 0
m := map[string]float32{
"p1":2.4, "p2":1.5, "p3":1.7}
for _,val := range m {
sum += val
}
fmt.Println(sum)
