Exported Names

In Go, a name is exported if it begins with a capital letter. For example, Pizza is an exported name, as is Pi, which is exported from the math package.

pizza and pi do not start with a capital letter, so they are not exported.

When importing a package, you can refer only to its exported names. Any “unexported” names are not accessible from outside the package.

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Println(math.Pi)
}
