sql - Two Column Data Structure - Python -

-

If I have a list of colors, how do I know about creating a data structure in a loop 

  [(u'blue ',), (u'green'), (u'black ',)]   
 and a data structure is required ( Maybe 2 ('blue', 'blue'), ('green', 'green'), ('black', 'black'))  
  code>  
 In addition, as an additional, why (and what kind of variable) is a list of my colors that is made with the items prefixed with you and they Surrounded When I try the string ops and do not recognize it as part of the string, the data comes from a pyodbc query on a column in SQL DB (not really color!).  
 For example if I was modifying the first row in colours_list (not the correct syntax)  
  line [2:] print row (u'ue ',) # Output   
 thanks!   
 
 
 Using generator expression and taple unpacking:  
  & gt; ; & Gt; & Gt; Color = [[('U', ''), (U'Green ',), (U' Black ',]] # If you want a Tuepal of Two-Item Tuples, then `Tupl ()` and Generator Expression & gt; ; & Gt; & Gt; Tupl (color, color for color), in colors) ((U'w ', U'blue'), ('U.Green', U'Grine '), (U' Black ', U'black')) # If you want a list of 2-item Tulips, use the list's understanding & gt; & Gt; & Gt; ['U' Grew '', 'U'Green'], (U 'Black', U'black ')] in colors [[color, color]] in color [ / Code>  
  U '...'  is a Unicode string literally (see)  
 Or you can use the  str  Object can be converted to:  
  & gt; & Gt; & Gt; Tupe ((color (color), str (color)) for color ('blue', 'blue'), ('green', 'green'), ('black', 'black')) & Gt; & gt; Color ('blue', 'blue'), ('green', 'green'), ('black', 'black') (color for color, encoded), color .encode ())))

ios - Adding an SKSpriteNode to SKScene from a child SKSpriteNode -

-
I have a SKScene where I am adding an SKSpriteNode I have subclassed the SKSpriteNode class to create this node. In the subclass I am defining some SKActions on Sprite. What do I want to do when the end of this phantom ends the SKAction sequence, then I add a new Prayer node to this scene. How is this possible. The following code is mine: The code for the sequence is that I'm running on the Scansprinitode subclass (TEMissileNode): - SKAction * moveDown = [SKAction moveToY: Self.position.y - 20 Duration: 0.2]; SKAction * animation = [SKAction animateWithTextures: textures timePerFrame: time / 7]; SKAction * moveMissileProjectile = [SKAction Moving: Pointoffscreen Term: Time]; SKAction * group = [SKAction group: @ [animation, movement projectile]]; SKAction * Sequence = [SKAction Sequence: @ [Hilldown, Group, [SKAction removalFromParent]]]; [Self run action: sequence]; From the main scene, I call those actions that execute these tasks TEMissileNode * missile = [tmissil...

Matlab transpose a table vector -

-
An embarrassing simple question seems to be, but how can I move a Matlab table vector? aTableT = aTable '; I tried a standard syntax for the simple interaction of a line vector to a line vector aTable : ATableT = reshape (aTable, 1, Height (aTable)); and aTableT = rot90 (aTable); According to the head, the last time table should work for table, see. However, I get this error code: Error type in using table / permit (line 396) Undefined function 'permute' for the input arguments. Error in rot 90 (line 29) b = magnitude (b, [2 1 3: ndims (a)]); NB: fliplr is not useful either pretty sure I have covered clear angles - any ideas? Thanks! Try changing your table into an array, move it, then back to a table In other words, try doing this: aTableArray = table2array (aTable); ATableT = array 2table (aTableArray. '); I have also read the document for rot90 , and it says that rot90 is definitely working for tables Do, and I find you...

c# - Textbox not clickable but editable -

-
I have a small form with 10 text boxes, I have set them in the correct tab order. I want them on my tab service I was wondering if there is a way to set the text box so that they can be selected for editing until they are tabbed. That is ... I do not want the end user to edit the text box to click on them, I just want to make them editable through tabu. this should do the trick public partial category poor text box: Text Box {Safe Override Zero WndProc (Ref: Message Message) {if (m.msg == (Int) WM.LBUTTONDOWN) {Return; // mount down events} base.WndProc (ref m); }} Window message enum can be found. How to do this without anherizing: text box : class EatMouseDown: netwindows {safe override zero WndProc (ref message message) {if (m.msg == (int) WM.LBUTTONDOWN) {return; } Base.WandProc (Ref M); }} Safe Override Zero Onload (EventEurge E) {base.OnLoad (e); How to do this without any part: left a clean part, whatever is important, this can be a buggy but it works R...
