我具有以下语法，但是每当在3.6中运行时，都会抛出错误：'_sre.SRE_Match'对象不是可下标的脚本在python3.7中工作正常，但在python3.6中出错

if {host}.issubset(sg_data['hosts'].split(',')):

    if sg_data['display_state'].lower() == 'offline':
        if dec_saved_data['display_state'].lower() != 'offline':
            yield from self.set_online(sg_data, host)
    else:
