• 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 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 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?

Note: in my computer all works well so maybe is some dll or file missing. I allready used Dependency Walker to see if there's some dll missing, and nop!

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

• 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!
