python - Trouble with getting data into JSON dict from html file -

i'm trying scrape website , far code has gotten me copied html code below. however, want access variable tablelist, 'defjson:' part , parse data in there. looks .split('\n') not working, splitting on spaces not work because data in defjson has random spaces. there other way access defjson?

<script type="text/javascript">     function _dozoom(t){         setcookie(fontcookiename,h,9999);         var a=document.getelementsbytagname("dl");         var k=[],c=[],g=[];         var b=a.length;         for(var f=0;f<b;f++){             if(a[f].getelementsbytagname("span").length>0){                 g.push(a[f]);k.push(a[f].getelementsbytagname("span")[0]);                 c.push(a[f].getelementsbytagname("span")[1])             }         }         b=g.length;         var e=document.getelementbyid("combinationscontainer");         switch(parseint(h)){             case 0:e.style.fontsize="14px";                 for(var d=0;d<b;d++){                     k[d].classname="at";c[d].classname=""                 }break;             case 1:e.style.fontsize="12px";                 for(var d=0;d<b;d++){k[d].classname="";c[d].classname="at"                 }break         }     }      var tablelist = new loadtable({         id: "dt_1",         sort: { id: "12", desc: true },         cells: [{ "n": "股票<font class=\"ssp\" style=\"text-decoration:           underline;\">代码</font>", "s": "5" }, { "n": "股票<font class=\"ssp2\">简称</font>", "w": "58" }, { "n": "相关资料", "w": "120" }, { "n": "申购<br />代码", "w": "44" }, { "n": "发行<br />总数<br />(万股)", "s": "7" }, { "n": "网上<br />发行<br />(万股)", "s": "8" }, { "n": "顶格申购<br />需配市值<br />(万元)<i title=\"黑色斜体部分为预估值，顶格申购需配市值的预估不涉及公司基本面分析，请谨慎参考。\">&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</i>" },          dataurl: "http://datainterface.eastmoney.com/em_datacenter/js.aspx?type=ns&sty=nsst&st={sorttype}&sr={sortrule}&p={page}&ps={pagesize}&js=var {jsname}={pages:(pc),data:[(x)]}{param}", ...         defjson:{pages:18,data:[",23772,80199130,万里石,002785,002785,50000000.00,20000000.00,,,,2015-07-08,2015-07-13,,,,,,,zxb,500.00,,,,,,http://topic.eastmoney.com/xmwlsipo/,中高端石材综合服务商&sbquo;一直专注于建筑装饰石材及景观石材的研发设计、生产和销售。,2.29,2.00,4.59,,0,,2.29,2,4.58,20.00,待上市,,,,,an201506250010008785,22.9,41.15" 

def scrape():     htmltext = open('test.html','r').read()     bs = beautifulsoup(htmltext)     scripts = bs.find_all('script')[-3]     print scripts 

so far code gets above part of html file tried adding in:

 line in scripts.split('\n'):       if (line.startswith('defjson: ')):           jsonstr=line.replace('defjson: ','')           datadict = json.loads(jsonstr) 

but gives me nonetype error there better way access defjson: part , load dictionary?
