python - Function inside a function - good idea? -

-

OK, let me reconstruct it to make it more theoretical - how do I separate duplication functions within the function. 

  def some_class: def out_fxn (): self.some_vars Here some values ​​are being used for each value: if type_A in the entry: get value , some_function (my_dict, dict_key, value) from the dict_index entry if type_ (get my_dict, dict_key, value) in type_: get value, dict_index entry, some_function (my_dict, dict_key, value) if entry in type_C: get value, dict_index entry  < class method?   some_function  (my_dict, dict_index, value) should be a  method of some_class ? It will not use any class member variable and do nothing with such a class like  
  •   nested function?   some_function  (my_dict, dict_index, value) can be inside out_fxn ()?  Nested functions ?   
     Note: I can loop on ABC, accordingly allocate values, but I just want to know that one way of doing this is using the function (object) : DEF out_fxn (auto): For entry in some_dict: 
     
      class some_class (object) ["type_A" self_tone_fiunction (some_dict, entry_key, entry_value) def some_function (self, my_dict, dict_key) in "type_", "type_", "type_A", "type_", "type_",: entry_value, entry_key = self.get_entry_stuff (entry type) , Value) def get_entry_stuff (self, entry_type): if the Return type = "type_a": return "one value", "single key" alip entry_type == "type_B": return "b value", "b key" alif entry_type == "type_C": return "c value", " C key "Other: Increase valueError (" I do not know about type:% s "% repr (entry_type))

    php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

    -
    I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

    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...
