I'm just full of questions today
by wheelege Dec. 13, 2000

Dec. 13, 2000

I've been trying to get global variables to help me, the way I've been getting around it is to pass local variables to a function through arguments - but that is going to get very unwieldy and messy. So, I decided to change my little section of code to give me an error about using a local variable before assignment. I think the error is because I tell it to change the value of the 's' variable to 's' + 1, which is using its own value to define itself which it might not like. Not sure though. And, as a side note - why isn't my window title 'yo'? Anyway, here is the little bit of code : from Tkinter import * root = Tk() root.title = "yo" s = 7 f = Frame(root) b = Button(root, text='hi', command=hi) f.pack() b.pack() def hi(): s = s + 1 print s

Your method definition is fine. The problem is with the line where you instantiate your object, or rather, don't. You need this: b= myTestClass() rather than: b= myTestClass The latter creates new reference to the myTestClass class, rather than creating on object belonging to that class.

Strange class behavior
by Darrell Brogdon Nov. 30, 2000

Nov. 30, 2000

Why is it that when I run the following script: class myTestClass: def myTestMethod(self): print "Test, Test, 1-2-3" b = myTestClass b.myTestMethod() I get the following error: Traceback (most recent call last): File "./test2.py", line 9, in ? b.myTestMethod() TypeError: unbound method must be called with class instance 1st argument Clearly I'm doing something wrong with the method definition but I've not been able to determine what?

Hello, I was able to use simple.py previously, but now it won't work. The only thing I've changed is that i've upgraded to Python Be Open 2.0. I've downloaded the most recent version of the installer (installer_b_03f.exe) and tried running SetupTK.py again. I receive an AssertionError while running SetupTK.py. Please help. Thanks Al

RE: [Tutor] sys.argv?

You aren't really passing it a number - you are passing it a string which happens to contain a number. So yes, basically, you are going to have to convert to a number using atio or some such.

directory listing and file mod times
by temp Nov. 28, 2000

Nov. 28, 2000

I'm making some progress with Mark Hammonds Win32 book, but on pp 311-312 there are listings that look like they would help in doing basic file/directory file mod time feedback, but I get this error. I actually understand the code up to the point of the 'decode_stat' part which Python gripes about anyway. I assume that there's a function or module that it refers to that I don't have? >>> os.stat('C:\Updates') (16895, 0, 2, 1, 0, 0, 0, 973065600, 973117026, 973117024) I get this far just fine...roll your own path, use os.stat on it and get the items back calculated since epoch. Now I write the function listed in the book, I just call my function 'fileinfo' instead of 'getfileinfo', which I hope is no grevous crime. I also didn't put in the code pertaining to file size or access, since my mission is geared to when last changes were made. (it should be simpler, right?) >>> import os, time, stat >>> def fileinfo(filename): ... modified = stats[stat.ST_MTIME] ... print 'last modified :' + time.ctime(modified) ... >>> decode_stat.fileinfo('C:\Updates') Traceback (innermost last): File "<interactive input>", line 1, in ? NameError: There is no variable named 'decode_stat' It blows up here. I don't understand where 'decode_stat' came from and apparantly neither does Python. Any ideas? (this could be 'operator error' related) Once I get this figured out, I can go on to working with 'walk'..which may generate as many questions..;) Thanks in advance, Larry Kuhn lkuhn(a)internews.org or codepuppy(a)internews.org
