r - Multiple array items appending -


यह प्रतिलिपि प्रस्तुत करने योग्य कोड है: 

  a & lt; - rep (1, 20) एक (सी (1, 12, 15)] & lt; - 0 b & lt; - जो (a == 0) सेट.सेड (123) डी & lt; - गोल (रूनिफ़ (17) * 100)  < / Pre> 
 मैं निम्नलिखित परिणाम प्राप्त करने के लिए  0  s को  d  जोड़ना चाहूंगा:  
  [1] 0 29 79 41 88 94 5 53 89 55 46 0 96 45 0 68 57 10 90 25   
 यह  d  को जोड़ने के बाद  0  के बराबर है > प्रत्येक तत्व के लिए   b - 1  के बराबर इंडेक्स है।  
 मैंने देखा है  अनुलग्नक ()  केवल "एकल" के बाद मान स्वीकार करता है एक से अधिक नहीं।  
 मैं कैसे कर सकता?  
 कृपया ध्यान रखें कि मैं  d  की लंबाई को बदल नहीं सकता क्योंकि यह माना जाता है कि यह इस उदाहरण में एक साधारण यादृच्छिक अनुक्रम की तरह नहीं, काफी लंबे फ़ंक्शन का ouput।   
 
 
 आप नकारात्मक उपयोग कर सकते हैं गैर-शून्य तत्वों को एक नया सदिश को असाइन करने के लिए सबस्क्रिप्टिंग।  
  डी & lt; - संख्यात्मक (लंबाई (सी (बी, डी))) डी [-बी] & lt; - डी डी # [1] 0 29 79 41 88 94 5 53 89 55 46 0 96 45 0 68 57 10 90 25

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
