[Tutor] Opensource projects / Subversion
Hey everyone, I finally made my way into working on Opensource projects. I installed tortoisesvn. I included command line tools when running the installer. However when I invoke svn at command line, I get the following error: "svn: command not found" It seems like svn isn't installed, but again, I had the installer include command line tools.

As Steven points out, this is more to do with installing particular development tools that with learning Python. However... TortoiseSVN is a popular Windows Shell extension offering easy access to Subversion via Windows Explorer. Although its installers have, for a long time, only offered Shell (in the Windows sense) access to the Subversion functions, more recent installers have offered to install the commandline svn tools as well. Since I have the commandline tools already installed, I've never actually selected this option when upgrading to newer versions. So what I don't know is whether they also add a suitable directory to the PATH environment variable. But, given the message you're getting, I imagine they don't. I suspect that they would install to somewhere like: %PROGRAMFILES%\TortoiseSvn\bin You can confirm that by cut-and-pasting that into your Start > Run menu or into an Explorer address bar and seeing if it comes up with a directory or not. If not, you'll have to scout around in likely places to see where it *has* installed svn.exe and its friends. Once you find them, add that directory to the PATH via: Control Panel > System > Advanced > Environment Variables depending somewhat on what setup you're running. And then try again at the command prompt with svn. Alternatively, don't bother with the command prompt; just use TortoiseSvn natively, so to speak.

This pattern works but the first should, too. shouldn't it?
The all too familiar quote looks like it applies here: "Often programmers,
when faced with a problem, think 'Aha! I'll use a regex!'. Now you have
two problems."
It looks like you could easily split this string with redata.split('::')
and then look at every second element in the list and split *that* element
on the last '.' in the string.
With data as well-formed as this, regex is probably overkill.

[Tutor] Calling Classes From Tkinter Radio Buttons
I'm using Tkinter for a GUI for a program of mine, and I'm trying to use radio buttons to select different functions, but it's not working right at all. Originally, I had something like class ClassOne(self): def ___str___(self): return "This is the base class." class ClassTwo(ClassOne): def __str__(self): return "This is the derived class." in, say, classes.py, and something like import classes from Tkinter import * class Application(Frame): def __init__(self, master): Frame.__init__(self, master) self.grid() self.widgets() LabelText = classes.ClassOne() def widgets(self): ClassLabel = Label(self, text = self.LabelText) ClassLabel.grid() root = Tk() app = Application(root) root.mainloop() in, say, GUI.py. This works perfectly fine, but it only sets the label as "This is the base class." What I'd like is a way to use radio buttons to configure the text of ClassLabel so that the user can choose between the two classes. Currently, I'm trying changing GUI.py to something like: import classes from Tkinter import * class Application(Frame): def __init__(self, master): Frame.__init__(self, master) self.grid() self.widgets() LabelText = classes.ClassOne() classes = ["ClassOne", "ClassTwo"] def widgets(self): self.variable = IntVar() ClassLabel = Label(self, text = self.LabelText) ClassLabel.grid(row = 0) ClassOneButton = Radiobutton(self, text = "This selects the base class.", variable = self.variable, value = 0, command = self.ChangeClass) ClassOneButton.grid(row = 1, column = 0) ClassTwoButton = Radiobutton(self, text = "This selects the derived class.", variable = self.variable, value = 1, command = self.ChangeClass) ResetButton = Button(self, text = "Reset the label", command = self.ResetLabel) def ResetLabel(self): self.ClassLabel.configure(text = LabelText) def ChangeClass(self): self.selection = self.variable.get() # This should get the value of the selected radio button, right? self.LabelText = self.classes[self.selection]() # LabelText changes according to the radio button. root = Tk() app = Application(root) root.mainloop() ... but when I run this, BOTH radio buttons are selected, and it still just gives me the base class. What am I doing wrong? Is there a way to first call a class with a radio button, and then reconfigure the label with that class? Any help that can be offered is appreciated! ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] regex question
I think you can do this:
a=[]
b=redata.split('::')
for e in b:
if e.find('@') != -1:
a.append(e.split('@')[1])
list a includes all the domain

[Tutor] Game of python, help please.
Hello all, Im trying to learn python and programming in my free time, and I'm trying to do a little personal project to trying and gain some skills. Im trying to do version of John conways game of life. I have a working version of the game. Written for 3.2.2 on a mac to be accessed through terminal. I'm trying to give it a number of options. it dimensions, the max number of turns, initial set up, and boundary conditions. The dimensions and turns were pretty easy to include. The boundary conditions more difficult, and now I'm getting stuck on the initial set up options. I can set it up randomly but Im having problems implementing a checker board pattern. '''displays: the text of the game of life for a set number of X x Y for a set of R turns. [-][-][-][-][-] [-][-][-][-][-] [-][-][-][-][-] [-][-][-][-][-] [-][-][-][-][-] Get X,Y,T, Initial value Create a data space X x Y Assign initial value print initial value and the text' initial value' do while turns iam.py Description: Binary data ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
