1import (2func main() {3    uid := osutil.UsernameToID("ankit")4    fmt.Println("User ID is: ", uid)5}6In the above program, the osutil package is imported using the import statement. The osutil package is stored in the same directory as the program. Hence, the package name is followed by a period. If the osutil package is stored in a different directory, the import statement would look like this:7import "github.com/ankitvgupta/Go-Practice/osutil"8osutil.UsernameToID("ankit")9We can also import the osutil package using the following syntax:10import (11import (12func UsernameToID(username string) int {13    u, err := user.Lookup(username)14    if err != nil {15        panic(err)16    }17    uid, err := strconv.Atoi(u.Uid)18    if err != nil {19        panic(err)20    }21}
