python - How to force every line to have the same # of tabs as the maximum length line -

-

I have a tab-delimited text, and I want to make tabs like the same number in each row have tab of the big number. For example, 

  a \ tB \ tC \ tD \ tF \ tG \ t   
 Input file: Will be  
  a \ tB \ tC \ tD e \ t \ t \ tF \ tG \ t \ t   
 I'm trying this is.  
  to import the Ayatr izip_longest import codecs inputf = sys.argv [1] outputf = sys.argv [2] as the F-open (inputf): data = izip_longest (* (* X.split ('\ t') for the line (* data) f), fillvalue = '\ t'): print line, offline = codecs.open (outputf, "w")   
 But there is nothing in the output, although it prints things in the command window.  
 I hope this program does not print in these command windows (it seems that takes a lot of time)  
 and I hope the output file has the right output .   
 
 
 Try using the CSV module, like this  
  #! / Usr / bin / env pyt import CSV Hein import System import Ijit_long def Reed_aro (Inputfail) with open (Inputfail, 'RB') H: reader = CSV. Reader (H, quote = "Excel-tab") returns List (Reader) def write_rows (Output, rows): open (Output, as' Wb ') H: Writer = Csvkwriter (H, quote =' Excel -tab ') for the row in lines: writer.writerow (line) def show_file (outputfile): Open (output file,' R ') as H (): h.read (). Splitlines () Diif main (input file, Output): rows = Ptar_pojh (Input File) rows = ZIP (* (izip_longest (* rows, fill = ''))) Write_rows (Outputfile, rows) Show_file (Outputfile) if __name__ == ' __main__ ': inputfile = sys.argv [1] outputfile = sys.argv [2] key (inputfile, outputfile)   
 with your input file:  
 < Code> ./in normally ~ / Downloads / input.txt ~ / Downloads / output.txt ['A \ TB \ TC \ tD', 'E \ t \ t \ t', 'F \ TG \ t \ t ']

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...
