At Trebas (Computer Hardware & Software Environment), the challenger proposed by Ghazal G.Fard starts with a WebServer in GoLang.
Before commenting on the code, we need to understand two differences between python and GoLang.
1) To "ignore" a line in Python we use # and in Golang we use // Some other languages like C, use #, and others, like PHP, use // or /* */.
2) In python I don't need to define the main() function.
We need to keep in mind that we need to develop clean code. For example, is a good practice to use MVC (Model, View, Controller) techniques.
On the code, we need to import three packages: "fmt", "log", "net/http"
The fmt package we use to give a response. Can be on screen, or in this case, a web response. For the log package, we are just writing a log. The net/http we use to start a webserver.
There are a lot of concepts that we can present in the future.

package main
import (
"fmt"
"log"
"net/http"
)
func main() {
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request){
fmt.Fprintf(w, "Hello!")
})
fmt.Printf("Starting server at port 8080n")
if err := http.ListenAndServe(":8080", nil); err != nil {
log.Fatal(err)
}
}
In this example, we do not use a concept of routes. Next week I'll start a new project to demonstrate rote on the GoLang web server.
Thank you for your time, and I hope that you can get an answer to your question.
