  - by eaigner

  Hi. I'm implementing a RESTful web service in python and would like to add some QOS logging functionality by intercepting function calls and logging their execution time and so on. Basically i thought of a class from which all other services can inherit, that automatically overrides the default method implementations and wraps them in a logger function. What's the best way to achieve this?

• python webtest port configuration?

  - by MattM

  I am attempting to write some tests using webtest to test out my python GAE application. The problem I am running into is that the application is listening on port 8080 but I cannot configure webtest to hit that port. For example, I want to use app.get('/getreport') to hit http://localhost:8080/getreport. Obviously, it hits just thits http:// localhost/getreport. Is there a way to set up webtest to hit a particular port?

• Getting logging.debug() to work on Google App Engine/Python

  - by brainjam

  I'm just getting started on building a Python app for Google App Engine. In the localhost environment I'm trying to send debug info to the GoogleAppEngineLauncher Log Console via logging.debug(), but it isn't showing up. However, anything sent through, say, logging.info() or logging.error() does show up. I've tried a logging.basicConfig(level=logging.DEBUG) before the logging.debug(), but to no avail. What am I missing?

• All possible permutations of a set of lists in Python

  - by Ian Davis

  In Python I have a list of n lists, each with a variable number of elements. How can I create a single list containing all the possible permutations: For example [ [ a, b, c], [d], [e, f] ] I want [ [a, d, e] , [a, d, f], [b, d, e], [b, d, f], [c, d, e], [c, d, f] ] Note I don't know n in advance. I thought itertools.product would be the right approach but it requires me to know the number of arguments in advance

• Why is "while" loop really needed in Python?

  - by Tomaž Pisanski

  I was told that 95% of all loops in Python are "for" loops. Since "while" loops are clearly more "dangerous" than "for" loops, I would like to know if there are situations in which the use of a "while" loop is essential. For teaching purposes it would be useful to know if there is a systematic way of transforming "while" loops into "for" loops.

  - by vailen

  I am currently get access to a cluster of Unix machines, but they don't have the software I need (numpy, scipy, matplotlib, etc), and I have to install them by myself (I don't have the root permission, either, so commands like apt-get or yast doesn't work). In the worst case, I have to compile them all from source. Is there any better way to do so? I hear something about Enthought Python and Sage, but not sure what is the best way to do so. Any suggestion?

• R or Python for file manipulation

  - by danspants

  I have 4 reasonably complex r scripts that are used to manipulate csv and xml files. These were created by another department where they work exclusively in r. My understanding is that while r is very fast when dealing with data, it's not really optimised for file manipulation. Can I expect to get significant speed increases by converting these scripts to python? Or is this something of a waste of time?
