python - read a text file and interpret the data -

-

I have to write a program that reads in a text file named "terms.txt" and then changes the file and It prints it with reference to the first page number. This is what the file looks like: 

  3: degree 54: connected 93: impending 54: top 19: side 64: neighboring 72: path 55: at least on the route 127: Tree 99: Spread Trees 19: Path 28: Connected 3: Degree 55: Graph 64: Approx 44: Width First Search 77: Neighborhood 55: Degree 55: Depth First Search 19: Degree 27: Neighborhood 16: Tree Tree   
 And after running through the program, it should do this:  
  imminent, 64 at 9.3 o'clock ago, 44 ​​added, 28, 54 degrees, 3, 19, 55 Deep search before depth, 55 edges, 19 graphs, 55 neighbors, 27, 64, 77 paths, 19,272 minimum routes, 55 spreading trees, 16 trees, 127 trees, 127 tops, 54   
 Right now, I have it and this page is printing a list of numbers and a list of contexts ... I'm not sure where to go from here to the file in the file: ==] = [] File = open ('terms.txt', 'r'): page number, reference ==  
  def bookIndex2 (): indexList = Line.split (':') pageNum .append (page number) indexList.append (reference) indexList.sort () Prints (Page New) Print (indexList)    
 
 
 You basically use any such dictionary Need to do, which shows the references of the list of page numbers in the map. As you repeat the file, add the page number to the list for that reference. Once you have processed the entire file, sort the software's contents and print them. I recommend using the standard dictionary instead because it is good enough to produce a dictionary of lists.  
  import from the archive with the default decode index = default (list) open ('terms.txt') as f: in line f: page, reference = line.strip () . Less (). Division (':') Index [Reference] .append (int (page)) For reference, sorted pages (index.items ()): Print "{}, {}". Format (context, ',' for sorted pages) (i HTML>

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...
