Find last occurrence of any item of one list in another list in python -

-

I have the following 2 listings in Python: 
  ll = [500,500,500,501,500,502,500] mm =  
 
 [4 9, 5, 5, 502]  < / pre> 
 In the list, I want to know the position of the last chance of any item. I can do this for one element:  
  lane (ll) - 1 - Ll [:: - 1] Index (502)> gt; & Gt; 5   
 Take here [:: - 1]. Indices (502) 502 provides last position and gives lane -1 total length.  
 How do I extend the entire list to work for mm? I know that I can write a function, but another dragon is the way   
 
 
 if you want  Last  Index   
  Ll =       ll  [500,500,500,501,500,502,500] mm = [49 9, 501502] d = {v: k for calculate in k, v (ll) if v in mm} # {501: 3, 502: 5}   
 Instead of o (n) it is possible to create a  set  to  set  before creating a (1) lookup, but three items For this, it is not really worth following the apro worries about maintaining unavailable index as  any  and make it a  O (1)  lookup Is using a hash lookup for. .  
  # Create a key- gt; Do not have any word for all `mm`d = dict.fromkeys (mm) - com d. For update (k), (v, v) enumerate (ll) if in v = d) # {499: none, 501: 3, 502: 5}

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i

I am trying to create Java web framework (and learning), and on the basis of 'Code Generator In the process of making the material view of the database in the process of development, I stumbled into a difficulty, which I do not know how to solve it.
