django 不能直接把列表给模板 TypeError: context must be a dict rather than tuple.

 将list 传递到前台模板:
 
 举例：

views.py

return render(request,'index.html',list)

def viewtbs(req):
   conn= MySQLdb.connect(
        host='127.0.0.1',
        port = 3306,
        user='root',
        passwd='1234567',
        db ='DEVOPS',
        charset="UTF8"
        )
   cursor = conn.cursor()
   a = cursor.execute("select sn,ip,info,env,script from publish_info;" )
   info = cursor.fetchall()
   print info
   print type(info)
   return render(req,'viewtbs.html',info)
