Why do I get the u"xyz" format when I print a list of unicode strings in Python? -


कृपया निम्नलिखित व्यवहार का पालन करें: 

  a = u "foo" b = u " B \ xe1r "# \ xe1 एक उच्चारण के साथ एक 'ए' है s = [a, b] print a, b प्रिंट s s में s: print x,

परिणाम है : 

  foo bár [u'foo ', u'b \ xe1r'] foo bár

जब मैं बस वैल्यू में बैठे दो मान मुद्रित करता हूँ < कोड> एक और b , मुझे मिल रहा है जो मुझे उम्मीद है; जब मैंने एक स्ट्रिंग मान को सूची में डाल दिया और उसे प्रिंट किया, तो मुझे अवांछित u "xyz" फ़ॉर्म मिलता है; अंत में, जब मैं सूची से एक पाश के साथ मूल्यों को मुद्रित करता हूं, तो मुझे पहले प्रपत्र मिल जाता है। क्या कोई इस प्रतीत होता है अजीब व्यवहार को समझा सकता है? मुझे पता है कि शायद एक अच्छा कारण है।

जब आप एक सूची मुद्रित करते हैं, तो आपको repr () प्रत्येक तत्व की सूची वास्तव में मुद्रित नहीं होती है, इसलिए अजगर इसकी संरचना के कुछ प्रतिनिधि को मुद्रित करने की कोशिश करता है।

यदि आप इसे किसी विशेष तरीके से प्रारूपित करना चाहते हैं, तो कैसे आप इसे स्वरूपित करना चाहते हैं, या इसकी __ repr __ विधि को ओवरराइड करना स्पष्ट है।

sql - dynamically varied number of conditions in the 'where' statement using LINQ -

I am using my first project LINQ (in mvc), so maybe there's something very simple that I remember. However, a day of searching and experimenting does not work, so it works. I am trying to write a LINQ query (Linux to SQL) in which in many cases where the statement is different from an OR or an AND. We do not know how many conditions are going in the query till runtime. This search is for filter control, where the user can choose multiple criteria for filtering. Select from table where table.col = 1 or table.col = 2 or table.col = 7 .... 'Other number of conditions Before I just create the SQL query as a string, while looping over all the situations. However, it seems that there should be a good way to do this in LINQ. I tried to use Expression trees, but they had a second thought for this moment on my head, where the lambda function was to be executed inside the statement such as: values ​​for matchingRows = matchingRows for each value Where (function (row) row.c...

asp.net mvc - Dynamically Generated Ajax.BeginForm -

I have a problem with ASP.NET MVC Ajax forms. I generate many Ajax form in a table such as: & Lt; Input type = "submit" name = "activity" value = "add activity" / & gt; & Lt;%}% & gt; & Lt; / TD & gt; & Lt; / TR & gt; & Lt;%}% & gt; So far so good. When I post one of those forms, it gives a partial view in a div, and in this new partial view a new Ajax Beginnform (which is not in Genesis form) This second Ajax Beginnorf is exactly like the ones I got on the table, but when I post it, I do not get the "Ajax Post", but a normal post that sends me to a new page, I do not know whether the two Ajax forms What is the reason for the difference between, why is it the "dynamically generated" Ajax form behaves like a normal HTML form? By the way, I know that I can do it in different ways using javascript, but I would like to understand whether it can only be done using MVC helplars and Ajax lib...
