[Tutor] curses
ok after reading a few tutorials i think i know enough to write my program here it is not commented yet though sorry: import curses from time import sleep scr=vurses.initscr() population=0 seconds=0 try: scr.nodelay(1) scr.leaveok(0) max_y, max_x = scr.getmaxyx() while scr.getch()== -1: sleep(1) seconds=seconds+1 population=population+2.5 scr.addstr(0,0,"seconds:",seconds") # i would like to get this bottom left but didn't know how scr.sddch(1,0,population) # here is ware i think I'm having problems also would like this to be centered scr.clear() scr.refresh() finaly: curses.endwin() but i get the error: traceback (most recent call last): file "population.py", line 15, in scr.addch(1,0,population) TypeError: argument 1 or 3 must be a ch or an int thank you ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] curses
hello all sorry to bother I'm working on my first curses program ive been wanting to learn curses for a while now and now that a have a lop top with fedora core running in run level 3 ware im trying to program all the tools i'll use but curses will be my only gui ALAN has been helping me with this program import curses from time import sleep scr=curses.initscr() population=0 seconds=0 try: scr.nodelay(1) scr.leaveok(0) max_y, max_x = scr.getmaxyx() while 1: sleep(1) second=seconds=+1 population=population+2.5 scr.addstr(0,0,"seconds",seconds) scr.addch,max_y/2, max_x/2, str(population)[0] scr.refresh() finally: curses.endwin() depending on ware i run this i get different results on may mac OSX 10.4 i only get a wired second thing in the top left corner that looks like this secooes and when i run this on fedora core 6 i get the seconds word in top left but no number and i get a single digit in the midle that changes i think the single digit is part of population but not all i cant find out what is wrong any help would be great :) ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

quick question how would i clear a text document? ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] clearing a text document
right it's for a quick math "game" the rules are simple you start with any number to get the next number you, a. if it's odd multiply by 3 than add 1 or b. if it's even divide by two, the point of this is to see how long it takes to get to one are it starts to repeat 4,2,1,4,2,1... now im looking for a a number with a very high amount of numbers till you get to 1 so every time it's finds a new one i would like it to write that to a file and clear the last entry, On Aug 29, 2007, at 5:45 PM, Alan Gauld wrote: > > "max baseman" <[EMAIL PROTECTED]> wrote > >> quick question how would i clear a text document? > > A bit of context?

Re: [Tutor] checking if a number is evan or odd
cool thanks thats what i changed it to than just now i changed to do something else and instead of leaving the program running for 4 or 5 days as i had been i got my answer in less than a second ^_^" i realized that i was wasting way to much time checking every possible answer because the number is jumping around so much so instead i wrote a real quick program infact i wrote it in interactive that just starts at 1 and works the problem backwards for how ever long i tell it to :)) thanks for considering the homework, but this time you did'nt have to worry i did the homework last week i was just doing this for fun, it randomly asked something like "what about a number that takes 100 steps to get to 1" and i thought what about 1000 :)) now i have one running looking for a number that takes 100 steps unfortunately i dont think ill get any extra credit for doing any of this lol here is the program sorry copying it from interactive: >>> number=1 >>> count=1000 >>> count=0 >>> while count < 1000: ... if (number*2)%2 == 0: ... number=number*2 ... else: ... number=(number-1)/3.0 ... count=count+1 ... print number On Sep 4, 2007, at 3:00 AM, Alan Gauld wrote: > Max, > >> just wondering if theirs a way to check if a larger number is even >> or >> odd > > I notice this is homework so I won't give a direct answer. > But look at the mod operator '%' - It returns the remainder > of an integer division.

hello all this is a homework in math i dont need to program it but i would like to :) so like any other time pleas dont just give a answer tutorials or a explanation. i dont like to use script something i dont understand :) thanks basically the problem is to find a bunch of ways to put 1,2,3,4,5 into different math problems to that equal 1-25, i haven't spent to much time thinking about how to do this but i cant think of a way to do it it without writing making the program rather long here is the page from the book for the rules i will be working on this for the next week or so thanks for any help :) . you may use any of the four basic arithmetic operations- addition, subtraction, multiplication, and division (according to the order of operations rules). for example, 2+1x3-4 is a 1-2-3-4 expression for the number 1. . you may use exponents. for example, 2² - 4 - 1 is a 1234 expression for the number 3 . you may use radicals for EX: √4x2+1 is equal to 3 so 3+√4x2+1 is a 1234 expression for 6 . you may use factorials for EX: 4! means 4x3x2x1 so 3+4!+1-2 is a 1234 expression for the number 26 . you may juxtapose two or more digits (that is put them next to each other) to form a number such as 12. for example 43-12 is a 1234 expression for 31 . you may use parentheses and brackets to change the meaning of a expression for example according to the rules of order of operations 1 +4x3² is a 1234 expression for 37. you can add parentheses and brackets to get [(1+4)x3]² which is a 1234 expression for 225 . must use 1,2,3,4 exactly once thanks for the help ill post if i find anything ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] Tkinter text
hello im working on my first simple gui using Tkinter i've got two questions, 1st how would you go about creating a hidden text file that trys on a apple and if that does not work tries to do it on a windows computer? the program I'm making is a vary simple text editor for one file all it needs to be able to do is add text and save. as far as i can see i'll mostly need to use the text widget but i cant find a tutorial for that widget mostly just for the text entry widget which is only for one line of text. if anyone knows a good tut that would be great thank you ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Tkinter text
sorry, what i was trying to say was, how would i write something that at first tries to create a hidden file on a apple computer then if the computer was not a apple creates a hidden file on a windows OS i have slowly been reading your tutorial and it's really one of the best tuts i've ever read i really like and that was the first place i checked but in the GUI section the text entry bit is for a single line of text On Oct 3, 2007, at 3:58 PM, Alan Gauld wrote: > > "max baseman" <[EMAIL PROTECTED]> wrote > >> i've got two questions, 1st how would you go about creating a hidden >> text file that trys on a apple and if that does not work tries to do >> it on a windows computer? > > I don;t undeetabnd this bit.

[Tutor] another quickie
hello all, im sorry but i might be asking a lot of Tkinter questions for a bit. im still working on my first GUI, it is very simple all i want it to do is open a text file, write to it, than save it. so far i have a GUI with the ability to right text (nothing amazing), but i don't know how to have it display the text from a text file any help would be great from Tkinter import * top=Tk() F=Frame(top) F.pack() F.txtBox=Text(top) F.txtBox.pack() F.pack() this is all i have so far ^_^" ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

[Tutor] powerball
as a fun little project i scripted a powerball program. it seems to have a bug in it that i cant find. from random import randrange wins=0 win=[] count =0 while count !=5: number=randrange(55)+1 win.append(number) count=count+1 powerball=randrange(42)+1 count=0 win.sort() while count !=146107962: numbers=[] count2=0 while count2 !=5: number=randrange(55)+1 if number in win: numbers.append(number) else: print "lose" break numbers.sort() ball=randrange(42)+1 if ball==powerball: print "win" print print print win, powerball ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] powerball
hello and thank you everyone for your help. I apologize for my ignorance when it came to knowledge of what the powerball is it is not as wide spread as i had thought it was the powerball is a form of lottery their are 5 numbers between 1 and 55, and then their is the powerball between 1 and 42 players win different amounts of money depending on how many numbers they had right the program i wrote uses the number 146107962 as the amount of tickets in play i found this number on the powerball stat as the probability of getting jackpot 1 / 146107962 included is the finished and working script if anyone would like to use or play with it. from random import randrange # for creating random numbers wins=0 # to see how many people would win win=[] # the winning numbers go here count=0 for count in range(5): # powerball uses 5 numbers win.append(randrange(55)+1) powerball=randrange(42)+1 count=0 while count != 146107962: # point of information useing for count in range(146107962) will overlaoad with this large a number numbers=[] # guesses count2=0 for count2 in range(5): number=randrange(55)+1 if number in win: # if the number is in the winning numbers continue numbers.append(number) else: print "lose" # else quite while ahead break numbers.sort() win.sort() ball=randrange(42)+1 #picks the powerball if ball == powerball: print "win" wins=wins+1 count=count+1 print print wins,"winners with", win, powerball seeing as i have left the python mailing list in the past any comments or ideas would be appreciated if sent to this email - thank you ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
