python - Django, calling function in re.sub -


मेरे कस्टम टेम्पलेटेट में इस लाइन है: 

  value = re.sub (r '(। *) \ (Bkz: (। *) \ B \)', r '\ 1 (bkz: & lt; a href = "/ baslik / \ 2" & gt; \ 2 & lt; / a & gt;), मान )

मैं अपने लिंक में slugify फंक्शन का उपयोग \ 2 को झुकावना चाहता हूं मैं यह कैसे कर सकता हूँ?

re.sub () या तो एक स्ट्रिंग या एक फ़ंक्शन को दूसरे के रूप में लेता है पैरामीटर में, आप जो चीजें चाहते हैं, उसके लिए आप एक फ़ंक्शन परिभाषित कर सकते हैं, नीचे एक बहुत तुच्छ उदाहरण है 

  value = "aaa1aaa" def slugifier (match_object): वापसी 'X' value = re उप ('\ d +', slugifier, मान) & gt; & gt; 'एएएक्सएआ' '

बस एक साइड नोट के रूप में, slugify \ 2 से बच जाएगा और खाली स्ट्रिंग का उत्पादन करेगा।

This is my code {{form :: select ('vehicles_year'), how the first selected value (in the selection box) will show. $ Model year, '-1', ['id' = & gt; 'Vehicles_year'])}} & lt; Span class = "help-block" id = "vehicles_year_error" & gt; @if ($ errors-> ('vehicles_year')) {{$ errors- & gt; First ('vehicles_year')}} @endif & lt; / Span & gt; -1 I am the default value key when I am showing the form load. What I do is that I add the "default" option which is "nothing" Is set to. In the validity rules, I say this value is necessary. If the user does not choose any of the other options, the verification fails. $ op...

Creating a sparse matrix in Matlab with a specified number of independent Bernoulli +-1 nonzero entries -

How can we create matrix x, 1000 by 1000 in the matteback, which is sparse, say Are, 5% of independent Bernoulli + 1 nonzero entries? I.e. In such a matrix, rho = = X Choose 5% of irregular elements n = Numel (x); Ind = Randie (n, round (.05 * n), 1); Assign these elements with random variables x (ind) = binorend (1, .5, length), 1) * 2-1; Check for more information To prevent duplicate rand numbers, from the Statistics Toolbox, or randperm as mentioned in some, or something like this Ind = []; T = round (.05 * n); T1 = length (IND); While T1 & LT; T Ind (end + 1: t0) = rand (n, tt-1, 1); Ind = Unique (Ind); T1 = length (IND); End
