Since I'm running Windows, I assume that I can't run the chmod line on my own computer. My web server uses Unix, but is it possible for me to have access to a command line for the server? I didn't know that was possible for basic web hosting plans (I'm using 1and1 right now). I suppose I could write a script that would set the permissions of all the files in a particular folder on my computer to 755, but is there a Windows equivalent command for chmod to do this? Or am I stuck having to do it on the server side?

Can I collapse a Panel in wxPython?
by nuffnough＠gmail.com April 30, 2006

April 30, 2006

Hi. I have a gui with one frame and 5 panels. The second panel will only be required in some cases, so I am wondering if there is some way I can only create this panel in the circumstances where it is required, confirmed by a simple len(list) > 1 If it is possible, I am wondering how I might go about it.... I am not sure where to put an if statement as there are many different referrals to panel_2 Letting me know or just pointing me to an example of such a thing would be fabulous. TIA

Hierarchy - how?
by veracon April 30, 2006

April 30, 2006

I'd like to know how to make the following string: food fruit red cherry yellow banana meat pork foo bar baz qux Result in a dictionary like this: {'food': {'fruit': {'red': 'cherry', 'yellow': 'banana'}, 'meat': 'pork'}, 'foo': {'bar': 'baz', 'qux': {}}} Or something like that (if you understand). What would be the best way of doing so? I'm thinking re.finditer might be appropriate, but I'm not sure. I'd prefer not looping TOO much, since it's actually made using a loop or two. Actually, if anyone has a better idea of how to do the entire thing, that'd be even better: def hierarchy(data, parent='', level=0, out=''): for item in which_parent(data, parent): out += ' ' * level + item + '\n' out = hierarchy(data, item, level + 1, out) return out def which_parent(data, parent): return filter(None, [item[1] == parent and item[0] or None for item in data]) data = (('food', ''), ('fruit', 'food'), ('red', 'fruit'), ('yellow', 'fruit'), ('cherry', 'red'), ('banana', 'yellow'), ('meat', 'food'), ('pork', 'meat'), ('foo', ''), ('bar', 'foo'), ('baz', 'bar'), ('qux', 'foo')) print hierarchy(data) -- Keep in mind that I don't want a string, I want a dictionary (but I can't figure out how to do it).

Converting tuple to String
by Byte April 30, 2006

April 30, 2006

Is their a command to convert a tuple to string? e.g. xyz = "Hello", "There" print xyz Is their any way of getting print to see xyz as being one string i.e. "Hello There" rather than "Hello" and "There", despite "Hello" and "There" being, in reality, seperate? Thanks in advance, -- /usr/bin/byte

best way to determine sequence ordering?
by John Salerno April 30, 2006

April 30, 2006

If I want to make a list of four items, e.g. L = ['C', 'A', 'D', 'B'], and then figure out if a certain element precedes another element, what would be the best way to do that? Looking at the built-in list functions, I thought I could do something like: if L.index('A') < L.index('D'): # do some stuff But I didn't know if maybe there was a preferred method for this type of operation, or perhaps a better function to use to figure out the ordering. Or even if I wanted to write my own utility function to make it look cleaner than above, I'd still need to use something like above in my function, so I wanted to know what might be the 'cleanest' looking solution. Thanks.

Re: how not use memmove when insert a object in the list

For a small number of list elements, by the time that memmove has determined (1) the move overlaps (2) both source and target are on word boundaries and it is moving a whole number of words (3) what direction (up or down), the DIY code has already finished. For a large number of items, memmove *may* be faster (depending on the architecture and the compiler) but you are using the wrong data structure anyway.

unable to resize mmap object
by Fabiano Sidler April 30, 2006

April 30, 2006

Hi folks! I created an mmap object like so: --- snip --- from mmap import mmap,MAP_ANONYMOUS,MAP_PRIVATE fl = file('/dev/zero','rw') mm = mmap(fl.fileno(), 1, MAP_PRIVATE|MAP_ANONYMOUS) --- snap --- Now, when I try to resize mm to 10 byte --- snip --- mm.resize(10) --- snap --- I get an EnvironmentError:[Errno 22] Invalid argument. How can I implement a resizeable anonymous memory mapping? Thanks for your reply! F. Sidler

ANN: Leo 4.4 rc1 released
by Edward K. Ream April 30, 2006

April 30, 2006

Leo 4.4 release candidate 1 is now available at: http://sourceforge.net/project/showfiles.php?group_id=3458&package_id=29106 This version fixes a few minor bug reported in 4.4b4 and adds 9 new commands. The open-outline-by-name command supports filename completion. Leo is a text editor, data organizer, project manager and much more. See: http://webpages.charter.net/edreamleo/intro.html The highlights of Leo 4.4: -------------------------- - An Emacs-like mini-buffer: you can now execute any command by typing its long name, with tab completion. - Many new commands, including cursor and screen movement, basic character, word and paragraph manipulation, and commands to manipulate buffers, the kill ring, regions and rectangles. You can use Leo without using a mouse. - Flexible key bindings and input modes. You can emulate the operation of Emacs, Vim, or any other editor. - A tabbed log pane. The Find and Spell Check commands now use tabs instead of dialogs, making those commands much easier to use. Plugins or scripts can easily create new tabs. The Completion tab shows possible typing completions. - Autocompletion and calltips. - Dozens of other new features and bug fixes since Leo 4.3.3.
