Re: split a directory string into a list

The most obvious case where it wouldn't work would be for a UNC path name. Using the string split method gives two empty strings: >>> os.path.normpath(r'\\machine\share').split(os.path.sep) ['', '', 'machine', 'share'] >>> whereas the splitpath function I proposed gives you: >>> splitpath(r'\\machine\share') ['\\\\', 'machine', 'share'] So to find out the type of path (relative, absolute, unc), you only have to consider the first element with my function but you have to look at the first two elements if you just naively split the string. Also a relative windows path with a drive letter doesn't get fully split: >>> os.path.normpath(r'c:dir\file').split(os.path.sep) ['c:dir', 'file'] >>> splitpath(r'c:dir\file') ['c:', 'dir', 'file'] If you really are worried about speed (and are sure you aren't optimising prematurely), then you could combine some special case processing near the start of the string with a simple split of the remainder.

Re: Flushing print()

Hello gf gf, Yes; you can use the '-u' command line option to Python, which will turn off stdout/stderr buffering. : If not, how can I flush it manually? sys.stdout.flush() didn't : seem to work. Hmmmm, that's odd. sys.stdout.flush() should do it. How are you testing that stdout isn't flushing as you expect? Best of wishes to you!

Pyallegro status (is it dead?). What about pygame.
by Przemysław Różycki Feb. 28, 2005

Feb. 28, 2005

Hi. Has anyone used pyallegro? - I want to give allegro library a chance - but it seems that python bindings for this library are not maintained anymore. How does pygame compare to pyallegro - both in maturity and convenience of usage in python?

netmask arithmetic?
by Dan Stromberg Feb. 28, 2005

Feb. 28, 2005

Before I go and reinvent the wheel, does anyone already have python code that can do netmask arithmetic - for example, determining if a list of hostnames are on subnets described by a list of networks+netmasks like: 128.200.34.0/24 128.195.16.128/25 ...and so on? Thanks!

parse lines to name value pairs
by sunriselee Feb. 28, 2005

Feb. 28, 2005

Hi all, I want to parse some string lines into name value pairs, where the value will be a list. Here are some sample lines: line1 = """path {{data/tom} C:/user/john}""" line2 = """books{{book music red} {book {math 1} blue} {book {tom's book} green}}""" For line1, the name is "path", the name-value should be the following forms: ["path", ["data/tom", "C:/user/john"]] For line 2, the name is "books", and the value should be a list in either one of the following forms (either one is ok): ["books", [["book","music","red"],["book","math 1","blue"],["book", "tom's book", "green"]]] or ["books", ["book","music","red","book","math 1","blue","book", "tom's book", "green"]] Any ideas? Many thanks!

Using PIL with py2exe
by John Carter Feb. 28, 2005

Feb. 28, 2005

Does anyone know how to embed PIL into a py2exe program. As far as I can tell PIL is not finding its plugins for Image I/O, they are imported dynamically as required. So I cant load or save pictures I tried making a copy of the plugin files to the application directory, but I've had no luck in making the code see the files I'd be grateful for any suggestion. Please e-mail me, as well as posting a reply. John Carter jnc(a)ecs.soton.ac.uk

TRUE PROVEN METHOD OF HIGHER INTELLGENCE alpha, theta and delta, brain waves of the mind wich we now know that are qunatium state of mind space time and realm. That froms the a beings instincts of unkown not found is the combination pleasent of sense's of smell,sight and sound in a peacesful manner..It is the consious ambient of peaceful manner that lead to intellgence. The relax state of mind and the brain wave patter that will be found will open a crative door to the minds eye not of what we think will be intellgence but during day dreaming states of mind. The person would be able to see the full design of ones idea with an open mind instead of starting with one concept and working with it you would be able to start with 10 concept and combine then as one. Itellgence is an I.Q that one can chart Because there are two types of people in the world people that dream and people that do and if dreams could learn to dream and then do. The definition of intellgence would change infromation flows free in this zeta multi-x pattern this would not just spawn another pattern of brain waves but would be one step into a door where infinte ideas of very high itellgence ones flow and cannot find the source, and tring to hard along with Hate puts more information in the brain that stops the flow of information the other sources that stops this infromation is P.S.I ability to do telepathy this is open you mind to unknown infromation. This path of this idea will give you the other infinte thoughts that you will never spawn from now until the end of time becuase no one has done this before and willl never do it but they have and try to intergrate hate and have fail where you my qunatum freind will succeed all other before us. This is the key to my qunatium encrypted web site.
