What would be the best way of removing any duplicate characters and sets of characters separated by spaces in string? I think this example explains it better: foo = 'h k k h2 h' should become: foo = 'h k h2' # order not important Other example: foo = 's s k' becomes: foo = 's k' etc. ...
I have been playing around with writing some simple card games in Python for fun and I would like to add a graphical user interface (GUI) to the games. Which library would you recommend for writing the GUI for a simple card game? ...
I'm trying to rename a file after it's uploaded in the model's save method. I'm renaming the file to a combination the files primary key and a slug of the file title. I have it working when a file is first uploaded, when a new file is uploaded, and when there are no changes to the file or file title. However, when the title of the file...
At the moment I have never had a problem with whitespace in Python (although I've only used it in two projects and I was the only programmer). What are some potential pitfalls with whitespace and indentation in Python for someone learning the language? ...
I've got a noisy python script that I want to silence by directing its stderr output to /dev/null (using bash BTW). Like so: python -u parse.py 1> /tmp/output3.txt 2> /dev/null but it quickly exits prematurely. Hmm. I can't see the traceback because of course that goes out with stderr. It runs noisily and normally if I don't direct ...
I admit the linux network system is somewhat foreign to me, I know enough of it to configure routes manually and assign a static IP if necessary. So quick question, in the ifconfig configuration files, is it possible to add a post connect hook to a python script then use a python script to reassign a hostname in /etc/hosts and spawn off...
I'm trying to get a trivial Django project working with Passenger on Dreamhost, following the instructions here I've set up the directories exactly as in that tutorial, and ensured that django is on my PYTHONPATH (I can run python and type 'import django' without any errors). However, when I try to access the url in a browser, I get ...
I have a source code in Fortran (almost irrelevant) and I want to parse the function names and arguments. eg using (\w+)\([^\(\)]+\) with a(b(1 + 2 * 2), c(3,4)) I get the following: (as expected) b, 1 + 2 * 2 c, 3,4 where I would need a, b(1 + 2 * 2), c(3,4) b, 1 + 2 * 2 c, 3,4 Any suggestions? Thanks for your time... ...
Hi everyone! I'm trying to add a simple "page x of y" to a report made with ReportLab.. I found this old post about it, but maybe six years later something more straightforward has emerged? ^^; I found this recipe too, but when I use it, the resulting PDF is missing the images.. ...
Hi, I have a list of tuples (always pairs) like this: [(0, 1), (2, 3), (5, 7), (2, 1)] I'd like to find the sum of the first items in each pair, i.e.: 0 + 2 + 5 + 2 How can I do this in python? At the moment I'm iterating through the list: sum = 0 for pair in list_of_pairs: sum += pair[0] but I have a feeling there must be ...
[Edit 2: More information and debugging in answer below...] I'm writing a python script to export MS Access databases into a series of text files to allow for more meaningful version control (I know - why Access? Why aren't I using existing solutions? Let's just say the restrictions aren't of a technical nature). I've successfully expo...
Hi I am in the field of data crunching and very soon might make a move to the world of web programming. Although I am fascinated both by Python and Ruby as both of them seem to be having every similar styles when it comes to writing business logic or data crunching logic. But when I start googling for web development I start inclining ...
Hi there I'm thinking about developing online multiplayer social game. The shared state of the world would require something fast on the backend, so the potential solutions seem to be: fast game engine on server (eg. c++ ) and some frontend language (php/python/ruby) + flash whole stack in python (using twisted or stackless python) + ...
I have a problem with combining or calculating common/equal part of these two dictionaries. In my dictionaries, values are lists: d1 = {0:['11','18','25','38'], 1:['11','18','25','38'], 2:['11','18','25','38'], 3:['11','18','25','38']} d2 = {0:['05','08','11','13','16','25','34','38','40', '43'], 1:['05', '...
I do not have stackless currently running, so I can not try this myself. import stackless ch1 = stackless.channel() ch2 = stackless.channel() ch1.send(ch2) ch3 = ch1.receive() Are ch2 and ch3 then the same channel? Say: text = "Hallo" ch2.send(text) assert text == ch3.receive() This feature reminded me of a talk about Newsqueak th...
For a website implemented in Django/Python we have the following requirement: On a view page there are 15 messages per web paging shown. When there are more two or more messages from the same source, that follow each other on the view, they should be grouped together. Maybe not clear, but with the following exemple it might be: An ex...
I have a simple task I need to perform in Python, which is to convert a string to all lowercase and strip out all non-ascii non-alpha characters. For example: "This is a Test" -> "thisisatest" "A235th@#$&( er Ra{}|?>ndom" -> "atherrandom" I have a simple function to do this: import string import sys def strip_string_to_lowercase(s...
I need to find names which contain three number 7 in the random order. My attempt We need to find first names which do not contain seven ls | grep [^7] Then, we could remove these matches from the whole space ls [remove] ls | grep [^7] The problem in my pseudo-code starts to repeat itself quickly. How can you find the names whic...
Suppose you have a python method that gets a type as parameter; is it possible to determine if the given type is a nested class? E.g. in this example: def show_type_info(t): print t.__name__ # print outer class name (if any) ... class SomeClass: pass class OuterClass: class InnerClass: pass show_type_info(Some...
Hello I'd like to have your opinion about writing web apps in PHP vs. a long-running process using tools such as Django or Turbogears for Python. As far as I know: - In PHP, pages are fetched from the hard-disk every time (although I assume the OS keeps files in RAM for a while after they've been accessed) - Pages are recompiled into o...
