problem with tkinter
by max(01)* March 30, 2005

March 30, 2005

hello. the following code: 1 from Tkinter import * 2 3 class MiaApp: 4 def __init__(self, genitore): 5 self.mioGenitore = genitore 6 self.i = IntVar() 7 self.i.set(42) 8 self.s = StringVar() 9 self.s.set("Baobab") 10 self.lab = {} 11 self.lab["self.i"] = Label(self.mioGenitore) 12 self.lab["self.i"].configure(width = 30, relief = RIDGE, 13 text = "[vuota]") 14 self.lab["self.i"].pack() 15 self.lab["self.s"] = Label(self.mioGenitore) 16 self.lab["self.s"].configure(width = 30, relief = RIDGE, 17 text = "[vuota]") 18 self.lab["self.s"].pack() 19 self.but = Button(self.mioGenitore) 20 self.but.configure(text = "Vai!", command = self.procedi) 21 self.but.pack() 22 def procedi(self): 23 for var in ("self.i", "self.s"): 24 self.lab[var].configure(textvariable = var) 25 26 radice = Tk() 27 miaApp = MiaApp(radice) 28 radice.mainloop() is intended to make a window with 2 labels and a button, such that pressin the button you get the labels display the content of two variables. it does not work, of course, as intended. is there anybody who can point me in the right direction? (the problem seems to be that the command option wants a variable name, not a string containing that name). hopefully macs

Optimisation Hints (dict processing and strings)
by poyol＠hotmail.com March 30, 2005

March 30, 2005

Hi all, I'd happy to have you share some thougts about ultimate optimisations on those 2 topics: (1)- adding one caractere at the end of a string (may be long) (2)- in a dict mapping a key to a list of int, remove every entrie where the list of int have of length < 2 So far, my attempts are for (1): >>>longone=longone + char # where len(char)== 1 I known that string concatenation is time consuming, but a small test on timeit seems to show that packing and creating an array for those 2 elements is equally time consuming for (2): for k in hash.keys()[:]: # Note : Their may be a lot of keys here if len(hash[k])<2: del hash[k] Here again, I think the hash.keys duplication can be time *and* memory consuming. But still better than (I suppose - no time it yet) hash=dict([(k,v) for (k,v) in hash if len(v)>1]) I know that I can experiment further with timeit, but still would like to hear from your experience. Thanks ! --OPQ

by Franz Steinh�usler March 30, 2005

March 30, 2005

Hello, I installed PyQt-win-nc-msvc-3.13.exe then complained: no, qt-mt230nc.dll, i found this and copied into system32 directory. I installed then: PyQwt_Qt333-4.2.win32-py2.4.exe Traceback (most recent call last): File "Grab.pyw", line 65, in ? from qt import * ImportError: Module use of python23.dll conflicts with this version of Python. Is there any version for Python 2.4? What shall I install to run pyqt? Second question: How can I achieve to switch betwenn Python23 and Python24 quickly? Many thanks in advance! -- Franz Steinhäusler DrPython (Project Developer) http://mitglied.lycos.de/drpython/

Re: What's the best GUI toolkit in Python,Tkinter,wxPython,QT,GTK?
by Fuzzyman March 30, 2005

March 30, 2005

Undoubtably Wax :-) Easier to learn than TKinter, with none of the limitations (it's built on top of wxPython). See http://zephyfalcon.org I've just started using it and I'm really impressed. Best Regards, Fuzzy http://www.voidspace.org.uk/python

oddness in string.find(sub,somestring)
by MyHaz March 30, 2005

March 30, 2005

OK i find this a quark in string.find that i think needs some consideration. Normally if a substring is not in the searched_string then string.find returns -1 (why not len(searched_string) + 1, i don't know but nevermind that) but what if a searched_string == '' ? Then string.find(substring,searched_string) == 0 ? example: >>> import string >>> searched_string="abcdefg" >>> substring="123" >>> print string.find(substring,searched_string) -1 >>> searched_string="" >>> print string.find(substring,searched_string) 0 >>> why would this be? And when is someone going to fix it :P - Haz

BF interpreter in Python
by Will McGugan March 30, 2005

March 30, 2005

Hi, Python is my favorite language, but I rarely get the opertunity to use it at work, so I find myself actively looking for problems to solve with it. Consequently while waiting for C++ build to finish, I wrote a BrainF*** interpreter. If you are not familiar with the BF language see the following example, which calculates the mandlebrot set.. http://esoteric.sange.fi/brainfuck/bf-source/prog/mandelbrot.b My BF interpreter is here.. http://www.willmcgugan.com/brainfuck.py Release to the public domain! I imagine somebody has already done this in Python, and I fully expect some Python expert to give a one line generator expression with the same functionality.. Will McGugan
