golang追加语法错误：标签后缺少语句[关闭]

Question

    fmt.Print("Text to send: ")
    text, _ := readerConsole.ReadString('
')

    sizen := (int)(unsafe.Sizeof(text))
    fmt.Print(sizen)
    var bs []byte
    binary.BigEndian.PutUint32(bs, sizen)

    b := []byte(text)
    a: = append(bs, b...)

Go formatter says error "syntax error: missing statement after label" on append

Answer 1

There's syntax error mate. Should be a := append(bs, b...) mate.
