Re: [Tutor] Print Output Location in Windows XP
Tom Strickland napsal(a): Up until now I have been running my Python programs in Linux. I just wrote one in Windows XP and I can't find the print output. The Python program has a print statement, and when I run the program a black window opens and I can see printing going on. However, when it's finished printing, the output window closes. How do I get the output window to stay open, or where is the output stored? You could: * put raw_input() statement on the last line in your program * run python with -i argument . i means stay interactive after run. example : python -i myfile.py Hope this helps -- geon ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Event handler for optionmenu
Jorge Louis de Castro napsal(a): Hi, Thanks for your reply. It wasn't lazyness, believe me, I did look around for solutions and found something similar to yours here: http://www.astro.washington.edu/owen/TkinterSummary.html#TracingVariables The problem is that I have a class and it wants the callback function to be a global name (I also can't figure out hot to pass parameters to it) By being a global name I can't access the var with widget.getvar(), and it complains if I use root by saying: Exception in Tkinter callback Traceback (most recent call last): File C:\Python24\Lib\lib-tk\Tkinter.py, line 1345, in __call__ return self.func(*args) File C:\Workplace\python\piim\Tkclient.py, line 312, in doLangChoices varValue = root.getvar(name) AttributeError: Tkclient instance has no attribute 'getvar' Not sure what Tkclient() is... seems to be not child od Tk(), cause there is no getvar() function... Anyway I am not able to run your script cause you used there both tabs and spaces for indentation. (see the row OPTIONS = [en,pt,es,it,fr,de], how much it is intended) Shoudnt be there varValue = self.startw.getvar(name)? - just guessing - I can not check cause the indentation i scorrupted ;-) geon ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] How can I make this run right?
Nathan Pinno napsal(a): I put in a 4 and expected 24, and instead got 12.

Here it is. There is one add and two changes. Can you see them? n = int(raw_input(Number: )) x = n-1 t=n while 1: t = t*x if x 1: x -= 1 else: break print t Its not the best solution for number!, but it is yours (and a bit of mine :-) ) -- geon ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] Tkinter event for changing OptionMenu items
Bernard Lebel wrote:
Hello,
I'm trying to bind an event to the changes made to an OptionMenu. Ie
the user chooses a different item, the rest of the Tk window gets
updated. To repopulate the window, a function would be called by the
binding.
Any suggestion?
var1 = StringVar()
var1.set( aTables[0] )
oOptionMenu = OptionMenu( oRoot, var1, aTables[0], *aTables[1:] )
sTableName = var1.get()
oOptionMenu.bind( 'Return', getTableColumns )
oOptionMenu.pack( fill = X )
I might know what you mean - binding optionMenu with say
w.bind('ButtonPress-1', tisk) is too early, it is called not after
the choice, but at the beginning, at clicking on the button.
I found curious solution, here it is: (maybe it could be done
otherwise, I would like to know, too..):
from Tkinter import *
OPTIONS = [
egg,
bunny,
chicken
]
def callmeagain():
global state
if state!=var.get():
print var.get()
state=var.get()
root.after(1000, callmeagain)
root = Tk()
var = StringVar()
var.set(OPTIONS[2]) # default value
state=var.get()
w = OptionMenu (root, var, *OPTIONS)
w.pack()
callmeagain()
root.mainloop()
Maybe this could help, too.

Re: [Tutor] Why does my code show this?
Nathan Pinno napsal(a):
cal_opt = int(raw_input("What option would you like: "))
if cal_opt == "1":
..
your problem is in these two lines (and even more, but if you solve
this, the others you get for free).
try run just these two lines and guess, think about what kind of
variable is in cal_opt.
elif cal_opt == "2":
X = input("First number:" )
Y = input("Second number:" )
print X, "-", Y, "= ",X - Y
cal_opt = int(raw_input("Option: "))
the other trouble might be on the last line - note that "if" is not
"while". :-)
before creating your own program would be better to go through some
nice tutorial, to get some experience.

Re: [Tutor] And function

Message
I need to write a program that
will do the following:
Ask the user's age.
If their age is below 1 yr old,
it prints "you are old enought to eat baby food"
If they are over 16, it prints
"You are old enough to drive"
If they are over 65, it prints
"You are old enough to drive" and "You are old enough to retire"
If they are between the ages of
16 and 25, it prints "you are old enough to get a student discount".
So far, I have this:
what about this:
age =input("How old are you?")
if age16:
print "You are old enough to drive!"
if age65:
print "You are old enough to retire!"
if age1:
print "You are old enough to eat baby food!"
If's those are on the same logical level should be also on the same
vertical level :-)
