I wrote the below code

    def idna_encode(name):
        "\n                                Borrowed    wholesale    from    the    Python    Cryptography    Project.    It    turns    out\n                                that    we    can't    just    safely    call    `idna.encode`:    it    can    explode    for\n                                wildcard    names.    This    avoids    that    problem.\n                                "
        import idna
        for prefix in [u'*.', u'.']:
            if name.startswith(prefix):
                name = name[len(prefix):]
                return (prefix.encode('ascii') + idna.encode(name))
        return idna.encode(name)
    name = idna_encode(name)
    if (sys.version_info >= (3, 0)):
        name = name.decode('utf-8')
    return name

What's a good function header?
 ... Can you provide a Python code to fix in [u'*?
