networkx - Iterating through and changing nested list entries in Python -

-

Everyone is writing a simple function in Python 2.7, which is to test using the Networks 1.9 module My graph algorithm implementation works correctly. For this, I have a list, Divix, in which there is a list for each block in the division of lists, which gives information about the edges of each node in the classes in the partition. Take a swan:

Block in the list block: block no = p.index (block) dvecs [blockNo] = [[-1] * numBlocks] * lane for node in block: node = block for other.index (node) p P: Other block nozz = P.index (otherBlock) dvecs [blockNo] [nodeNo] [otherBlockNo] = len (set (nx.neighbors (G, node)) intersection (set (other block))

The problem that comes to me That is, in the last row of the nested loop, the line begins with DVC [block non ...], according to the debugger, each entry from the center depth list (one node specified by the node specified in the index) interval For each recurrence of the loop, it is being updated with the same value. In other words, it seems that the 'node' is being kept continuously and all the nodes in the block are node nodes Moving. What is happening?

In response to the Romans, I tried the following: Block 

 , in the number (P) for the block: dvecs [blockNo] = [[-1] * Numblocks] * Node for node, node in enumerate (block): For other blocks, enumerate in other blocks (p): dvecs [blockNo] [nodeNo] [otherBlockNo] = len (set (nx. Neighbors live, node)). Intersection (set (other block)))   
 However, I am receiving the same behavior. Did I forget something?   
 
 
 this:  
  [[]] * n   
 provides you with a list of  same  empty list,  n  bar, then adding "none" to all of them by adding one of them There is a nested list.  
 Try it out, which will create separate blank lists:  
  [[_ for category]]

I do not know how to use mysqli_result like in the past. Is this OK? How is right WHERE status = 'popup' and creditsp> = 1 and (CH) from $ res = mysqli_query ($ con, "SELECT` id`,` usrid`, `url` site Lt; cf || cf = 0) sequence by rand () border 1 "); $ Urll = mysqli_result ($ res, 0, "url"); $ Ownerid = mysqli_result ($ res, 0, "Elixir"); $ Citid = mascile_salt ($ res, 0, "id"); Use fetch_assoc on the results: $ line = $ res-> gt; Fetch_assoc (); $ Urll = $ line ['url']; $ Owner = $ line ['nectar']; $ Site id = $ line ['id']; If there are more than one line, then: while ($ line = $ res-> fetch_assoc ()) {// process $ Line}

Delphi: missing interface declarations for UI Automation methods -

-
Such a basic question is, but I'm stuck ... I get I'm trying to start with UI Automation using Delphi 2007 (Win32) on Windows 7. It seems that I do not have to use some methods and types. I have the .NET Framework 4.x installed on this machine, but I have imported a type of library from the C: \ Program Files (x86) \ reference assembly \ Microsoft \ Framework \ v3.0 \ UIAutomationClient.dll ... ... I am looking for UIAutomationClient_TLB: UIAutomationClientMajorVersion = 1; UIAutomationClientMinorVersion = 0; I'm not sure that this is the problem (wrong version). I can declare the following with no problem: var UIAuto: IUIAutomation; Element: IUIAutomationElement; But the methods of IUIAutomationElement are missing. For example, there is nothing in the interface declaring this method: IUIAutomationElement.TryGetCurrentPattern () ... which msdn.microsoft According to .com, there is an interface method which is returning to at least NET 3.0. Where do...
