[Tutor] Python programming activities
Are you familiar with Kakuro (Cross Sums)? See http://www.kakuropuzzle.com/ for an example. In every such puzzle the top row and left column are all "black". I exclude these from the following "rules": A valid puzzle meets the following rules: 1 - black squares are symmetric around center. (thus ditto for white). 2 - every white square has at least one white square neighbor vertically and horizontally. 3 - there is a path from any white square to any other white square. 4 - the upper left square is black 5 - there are at most 9 contiguous white squares. 6 - a black square followed horizontally by contiguous white squares has a number in its upper right corner that is the sum of the digits to be placed in the contiguous white squares. 7 - ditto for vertically, the number going in the lower left. 8 - there must be at least one combination of unique digits that totals to the expected sum. 9 - there must be one and only one solution to the puzzle that meets all expected sums. This leads to an interesting series of programming assignments. You would start with some # of rows and columns. Each time the program would print the result. Aim for a simple character representation of the board. Example: 1 2 3 4 +-+-+-+-+-+ |X|X|11\XX|10\XX|X| +-+-+-+-+-| 1 |X| 3\4 | | | 7\X | +-+-+-+-+-| 2 |XX\12| | | | | +-+-+-+-+-| 3 |XX\10| | | | | +-+-+-+-+-| 4 |X|XX\5 | | |X| +-+-+-+-+-+ There are many ways to represent such a puzzle. I offer the following list of lists where - 0 = black with no numbers - 0.r = row sum - c.0 = column sum - c.r = row and column sums - -1 = blank white square - any integer between 1 and 9 = white square with number (potential solution) Given that the above puzzle would look like: [[0,0,11.0,10.0,0], [0.3.4,-1,-1,7.0], [0.12.-1,-1,-1,-1], [0.10.-1,-1,-1,-1], [0,0.5,-1,-1,0]] Assignment - Solve one or more of these puzzles, if you are not familiar with them. Assignment - Take the above list representation of the puzzle and print the human-readable form as shown above. Assignment - Program for human to enter the layout of a puzzle. Assignment - Look up the shelve module. This is an easy way to save and restore Python objects. This will be very useful to save puzzles that are in progress and restore them later. Write a simple program to save and restores some trivial object. Assignment - Apply the shelve technology to save & restore puzzles. Assignment - Program for human to enter value(s) for a square, using the row and column number to identify the square, and to print the result on demand. Assignment - Evaluate the solution to see if all the sums are correct. Report errors. Assignment - Design a structure that would be indexed by a potential sum and # of contiguous white squares to contain the potential solutions for that combination. Example for sum = 5 and # squares = 2 ((1,4),(2,3)). Assignment - Fill that table with the potential solutions. Assignment - Use that table to put values in rows and print a potential solution to a puzzle. Assignment - Think of ways to optimize automated solving of a puzzle rather than just brute force trial-and-error. I realize that this can go on and on. I hope this is in the ballpark of sufficient interest and somewhat easy steps.

[Tutor] Tkinter Icon Suse 10
Hi everyoneIt's been a long time since I left Python for .NET 2003, but then again I need it to make an app under Linux Suse 10 and I have a questionI'm trying to put an icon to my window...Here is the code so far:
###Start Code###import Tkinterfrom Tkinter import *root = Tk()root.iconbitmap("Change.ico")root.mainloop()###End Code###It works great under Windows but on an Suse 10 Machine it complains about the file. Is this because the icon files are not the same as in Windows or should I be using another sentence to make it work?
I know it's a dumb question but I'm out of practice and I couldn't find docs on Google (maybe I didn't look where I supposed to)Ups..I forgot, I'm using Python 2.4.1Regards-- Alberto

Re: [Tutor] What's the invalid syntax?
Nathan, > Sorry, but it only showed a text-box with the message "Invalid > syntax!", then highlighted the %. OK, But if you try it from a command prompt you will get a proper error message. But even if you tell us which line it is highlighting, there are several % signs in your code. Generally when pythonindicates a syntax error it will be within a few lines of where the error occurs, so iut saves us a lot of reading!

If you don't know about list comprehensions, you can read about them in any python tutorial. >>> x = [1, 2, 3, 4, 5] >>> y = [str(i) for i in x] >>> y ['1', '2', '3', '4', '5'] Then you can use the .join() method of strings to join them into a single line. In this case, the separator is a space, ' ': >>> z = ' '.join(y) >>> z '1 2 3 4 5' If you want to put one number on each row, you can use the newline character '\n' as a separator instead: >>> '\n'.join(y) '1\n2\n3\n4\n5' >>> print '\n'.join(y) 1 2 3 4 5 HTH! -- John. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Hi Alberto,
you will have to use an xbm bitmap file for the iconbitmap, like
root.iconbitmap("@Change.xbm")

Certainly more than mine Wes! I got a lot of flack on amazon reviews for not putting exercises at the end of each chapter - although in fact there are over 50 "challenges" throughout the text, but you have to read the text to find them! ( That's because I don't like text book style exercises personally...) However one badly missed Python resource that used to help a lot was the Useless Python web site. Alas it seems to have dissappeared fromthe web. The author tried to do a revamp and for some reason version 2 never quite got the support the original site did. But it was a great resource of little mini-projects and challenges for beginners. And of course the Python Challenge game is still on the web, but the challenge there tends to be in figuring out what to do, once yopu get past that you can write the code in about 5 minutes flat! The other problem is you usually need to paste the result back into a webn browser to assess the result! Alan G. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] tkinter events:
So, in the following line

the event-handler will call handler(event, 'release') when the

passed over, so the result will be the handler(self,event, 'release')
call.
