Imports

This code groups imports into a parenthesized, “factored” import statement. You’ll see this pattern everywhere in Go code.

You could write separate import statements instead:

import "fmt"
import "math"

But the factored style is preferred — it’s cleaner and easier to scan.

main.go ▶ Run in Playground 
package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Now you have %g problems.\n", math.Sqrt(7))
}
