• ctypes buffer modification

  - by Chris

  Hi, I need to call a c library from my python code. The c library does a lot of image manipulation, so I am passing it image buffers allocated using create_string_buffer. The problem is that I also need to manipulate and change these buffers. What is the best way to reach in and twiddle individual values in my buffers? The buffers are all uint8 buffers. Thanks!

• Does OOP make sense for small scripts?

  - by Fabian

  I mostly write small scripts in python, about 50 - 250 lines of code. I usually don't use any objects, just straightforward procedural programming. I know OOP basics and I have used object in other programming languages before, but for small scripts I don't see how objects would improve them. But maybe that is just my limited experience with OOP. Am I missing something by not trying harder to use objects, or does OOP just not make a lot of sense for small scripts?

• How do I encode Unicode strings using pyodbc to save to a SAS dataset?

  - by Chris B.

  I'm using Python to read and write SAS datasets, using pyodbc and the SAS ODBC drivers. I can load the data perfectly well, but when I save the data, using something like: cursor.execute('insert into dataset.test VALUES (?)', u'testing') ... I get a pyodbc.Error: ('HY004', '[HY004] [Microsoft][ODBC Driver Manager] SQL data type out of range (0) (SQLBindParameter)') error. The problem seems to be the fact I'm passing a unicode string; what do I need to do to handle this?

• How to change last letter of filename to lowercase if it is a letter?

  - by Robert Buckley

  I have been given data which cannot be interpreted by my software unless it has a lowercase letter at the end. The data was delivered with an uppercase letter at the end. Somehow I need to first recursively loop through all folders and find whether the filename ends with a letter and then change it to lowercase. I think python could do this, but I don´t know how,. Any help would be great! yours, Rob

• How to create a named temporary file in memory?

  - by conradlee

  I would like to use Python's tempfile module to create a temporary file that I will use for communication between processes (use of pipes is awkward). The documentation I've linked to above shows two functions that almost do what I want: tempfile.NamedTemporaryFile # For creating named tempfiles tempfile.SpooledTemporaryFile # For creating tempfiles in memory but actually I want a tempfile that is both named AND in memory. Any ideas?

• How to find out the exact RSS XML path of a website?

  - by Winston

  How do I get the exact feed.xml/rss.xml/atom.xml path of a website? For example, I supplied "http://www.example.com/news/today/this_is_a_news", but the rss is pointing to "http://www.example.com/rss/feed.xml", most modern browsers have this features already and I'm curious how did they get them. Can you cite an example code in ruby, python or bash?

  The Python datetime.isocalendar() method returns a tuple (ISO_year, ISO_week_number, ISO_weekday) for the given datetime object. Is there a corresponding inverse function? If not, is there an easy way to compute a date given a year, week number and day of the week?

• I want to learn a new language!

  - by Alex

  Hi, I'm a college student majoring in computer science. I know java and will be learning C++ the next couple years at school. I want to add another language to my repertoire and have gotten conflicting advice: Ruby, Python, Perl, JavaScript, PHP, AJAX, among others. I was wondering what everyone's opinions were on the relative value of each of these languages in the job market, the ease of learning of each of the languages, and just personal preferences when it comes to the languages mentioned above. Thanks!

  - by morpheous

  Recently came across pidgin. Its great, and does what I want, but I am not too keen on the GPL license. Other any alternatives, with less restrictive licenses? I would prefer the library to be C or C++, as I am most familiar with those languages, but a an IM library implemented in python would be interesting too.

• How do I rename a process on Linux?

  - by jemfinch

  I'm using Python, for what it's worth, but will accept answers in any applicable language. I've tried writing to /proc/$pid/cmdline, but that's a readonly file. I've tried assigning a new string to sys.argv[0], but that has no perceptible impact. Are there any other possibilities? My program is executing processes via os.system (equivalent to system(3)) so a general, *NIX-based solution using an additional spawning process would be fine.

• 64-bit integers in Cython

  - by Homayoon

  I'm trying to interface a C++ library (pHash) with Python using Cython, but I have trouble with some of the types. The library functions use "unsigned long long" and I can't find a way to declare variables and parameters with this type. I searched for a list of the types that I can use with cdef but I found nothing. Can anyone point me to such a list (if it exists) or otherwise suggest a way to use 64 bit types in Cython? Thanks.

• Generate table schema inspecting Excel(CSV) and import data

  How would I go around creating a MYSQL table schema inspecting an Excel(or CSV) file. Are there any ready Python libraries for the task? Column headers would be sanitized to column names.

• Assigning IDs to instances of a class (Pythonic)

  - by mellort

  I want to have each instance of some class have a unique integer identifier based on the order that I create them, starting with (say) 0. In Java, I could do this with a static class variable. I know I can emulate the same sort of behavior with Python, but what would be the most 'Pythonic' way to do this? Thanks
