如何在Golang中将模板输出写入文件?

I use the following code which work ok, but now I want to print the template to a file and tried the following but got error

package main

import (
    "html/template"
    "log"
    "os"
)

func main() {
    t := template.Must(template.New("").Parse(`{{- range .}}{{.}}:
    echo "from {{.}}"
{{end}}
`))
    t.Execute(os.Stdout, []string{"app1", "app2", "app3"})

    f, err := os.Create("./myfile")
    if err != nil {
        log.Println("create file: ", err)
        return
    }
    err = t.Execute(f, t)
    if err != nil {
        log.Print("execute: ", err)
        return
    }
    f.Close()
}

The error is:

execute: template: :1:10: executing "" at <.>: range can't iterate over {0xc00000e520 0xc00001e400 0xc0000b3000 0xc00009e0a2}
