Python: function, passing argument -


I am new to python and I have a stupid problem to pass through logic. 

  class MyClass (): @staticmethod def add_group (name, parent_id): print "add_group method, name:% s, parent_id:% s"% (name, parent_id)   
 Other classes  
  def (): print "work method, name:% s, group_id:% s"% (name, parent_id) MyClass.add_group (name , Parent_id)   
 Output:  
  function method, name: blabla, group_id: 15 add_group method, name: blabla, parent_id: (15L,) < / Code>  
 What's happened with parent_id argument? Any help would be appreciated!   
 
 
 In one case you  15  in the second case you  (15L ,)  (i.e. a tubal whose first value is 15 L, it is passed long, representing (15) or a arbitrary-precise number 15).  
 When the number is very high, such as 10 ** 20, but in this case it is very small, then the number changes naturally in a long time; The only way I can think that you would have had a long time, you were not expecting that something was doing something like  10 ** 20 - 10 ** 20 + 15  Some other value in the program is a long one.  
  Edit : In particular, the second value in your program is being returned by the library you are using.

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...
