Re: [Tutor] Tutor Digest, Vol 106, Issue 74
Sorry, I should have been more clear in what I was trying to accomplish. I
am trying to build the latin square as follows:
1234567
2345671
3456712
4567123
5671234
6712345
7123456
So, the scaleorder is the n*n scale of the square - in this case, a 7x7.
The key is that there should be no duplicate number for each row and for
each column. And the topleft variable is the number in the topleft that
sets how the rest of the square will look - in the example I gave above, it
is 1.
The link below is the original exercise - I am not in school, purely for my
own education as I am really trying hard to become a passable Python
programmer. I've been working at it for 6 month now, and I don't know any
other languages:

Hi Randy
I am an older newbie teaching myself Python programming.
Me too :)
My problem is I hear no system bell; the enter doesn't respond by
quitting the program;
The problem with the program code the enter key hasn't worked in earlier
programs.
I appreciate any advice I may recieve with this coding glitch.
I copied the code into a blank .py file and ran it from cmd in Windows
XP x86 using Python 273, it worked fine - including the beep. As well,
hitting Enter exited the program.
It sounds like (no pun intended) it may be how you're running the
program. I would use a py file and run it using cmd - holler if you
need help, you may if the path to Python isn't good to go.
Mike

I am having trouble figuring out a solution after a couple hours now of
playing with the code. I'm trying to make a latin square using the code
below:
scaleorder = int(raw_input('Please enter a number for an n*n square: '))
topleft = int(raw_input('Please enter the top left number for the square:
'))
firstrow = range((topleft),scaleorder+1)
count = 0
while count 8:
for i in firstrow:
print i
count += 1
firstrow[i+1]
---
It seemed like I could make the for loop work by doing something like this:
for i in firstrow:
print i, i+2
but that obviously is not a solution either. Any ideas?
Thanks,
Brandon

This way your new message will be threaded together with the previous ones. And for those unable to see the threads, at least the subject line will match. Note the first line below of the quote you used: On Mon, Dec 31, 2012 at 3:00 AM, tutor-requ...@python.org wrote: snip When replying, please edit your Subject line so it is more specific than Re: Contents of Tutor digest... So you don't just want a latin-square, you want a particular one. You picked the most trivial one, where all the spots are numeric, and each line is simply sequentially chosen from a ring, 1 through scaleorder. Assuming scaleorder is less than 10, the following should work. table = [str(i) for i in range(1, scaleorder+1) * 3] for row in range(topleft-1, topleft+scaleorder-1): line = table[row:row+scaleorder] print .join(line) If you have to deal with scaleorders bigger than 9, then you'll need a separator between the numbers. Probably the easiest place to fix that would be in constructing the table. But a qd fix might be to use .join() on the last line. -- DaveA ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Brandon, Please trim your response to only the parts of the email that are actually relevant. As given, you have duplicated SIX emails which we have already seen and don't need to see again, at least not in full, multiple hundreds of lines of text. Also, please ensure that you use a sensible, meaningful subject line. Re: [Tutor] Tutor Digest, Vol 106, Issue 74 means nothing. More below.

So start off by writing down how you would do this in ordinary English: Step 1: Write down the list 1234567. Step 2: Take the digits above, move the first digit to the end, and write it down. Step 3: Repeat Step 2 five more times. (Six times in total.) Now try turning that into Python code.

Re: [Tutor] Please help
I saw the code; I see too many formatting errors: Line No 24 starts a function definition and the next few lines are indented by two spaces, but Line 29 is a print statement that is in line with the def; IOW it completes the function. It is very likely wrong. You are defining functions within functions; again it is very likely to be wrong. My advice, look at PEP 8 and also some sample python code in the tutorial to understand how to format code. Remember: Leading whitespace is syntactically significant HTH Asokan Pichai Religion offers hope against all the strife and misery of the world caused by religions. ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
