import "fmt"
func main() {

    var shoppingList = map[string]string{
		"Name": "Deidre Haider", 
		"Address": "631 Grand Avenue Glendora, CA 91740",
		"Phone": "202-555-0150",
		"Email": ""}
    for key, element := range shoppingList {
        fmt.Println("Key:", key, "=>", "Element:", element)


For each iteration you can access the key and its correlated element value.

To compile the code navigate to the file location and run the following command.

$ go build example.go

Assuming that example.go is the name of your file.

Then depending on if you are on Linux or Windows the binary file is created.

To run the application, execute the command.


$ ./example


c:\Users\adm\go\tutorials> example.exe

If you want to compile and run the application in one single step, run the following command:

go run example.go
