If in Python I put a list inside a tuple, can I safely change the contents of that list? -

    टपल के अंदर का मान है बस एक सूची के लिए एक संदर्भ है, और अगर मैं सूची में मूल्यों को बदलने के लिए सब कुछ क्रम में अभी भी है, है ना? मुझे यह सुनिश्चित करना है कि यदि मैं ऐसा करता हूं तो मैं भ्रमित त्रुटियों में चलना शुरू नहीं करूंगा।

    ट्यूपल्स अपरिवर्तनीय हैं, आप उनकी सामग्री नहीं बदल सकते हैं।

    एक सूची के साथ 

      & gt; & gt; & gt; X = [1,2,3]> gt; & gt; & gt; X [0] = 5>> gt; & gt; एक्स [5, 2, 3]   
     एक ट्यूपल के साथ  
     > gt; & gt; Y = ट्यूपल ([1,2,3])> gt; & gt; & gt; Y (1, 2, 3) & gt; & gt; & gt; वाई [0] = 5 # अनुमति नहीं है! ट्रेसबैक (सबसे हाल का कॉल अंतिम): फ़ाइल "& lt; pyshell # 20" gt; लाइन 1, & lt; मॉड्यूल & gt; Y [0] = 5 प्रकार त्रुटि: 'ट्यूपल' ऑब्जेक्ट आइटम असाइनमेंट का समर्थन नहीं करता   
     लेकिन अगर मैं आपका प्रश्न समझता हूं, तो कहें कि आपके पास  
      & gt; & gt; & gt; A = [1,2,3]> gt; & gt; & gt; बी = [4,5,6]> gt; & gt; & gt; टी = (ए, बी)> और gt; & gt;            > <कोड> & gt पूर्व; & gt; & gt; टी [0] [0] = 5>> gt; & gt; टी ([5, 2, 3], [4, 5, 6])

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
