python - Lineの編集ボット

Question

https://github.com/merkremont/LineVodkaからボットスクリプトを入手しました

このスクリプトを追加したいのですが、構文エラー/予期しないインデントと表示されます

elif msg.text in ["Tag all","Tagall"]:
    if msg.from_ in admin:
        group = client.getGroup(msg.to)
        nama = [contact.mid for contact in group.members]

        cb = ""
        cb2 = ""
        strt = int(0)
        akh = int(0)
        for md in nama:
           akh = akh + int(6)

           cb += """{"S":"""+json.dumps(str(strt))+""","E":"""+json.dumps(str(akh))+""","M":"""+json.dumps(md)+"},"""

           strt = strt + int(7)
           akh = akh + 1
           cb2 += "@nrik \n"

        cb = (cb[:int(len(cb)-1)])
        msg.contentType = 0
        msg.text = cb2
        msg.contentMetadata ={'MENTION':'{"MENTIONEES":['+cb+']}','EMTVER':'4'}

        try:
           sendMessage(msg)
        except Exception as error:
           print error
