  • Best (or appropriate) WSGI server for this Python script? - Python

    - by RadiantHex
    Hi folks, I'm having quite a problem deciding how to serve a few Python scripts. The problem is that the basic functionality could be generalized by this: do_something() time.sleep(3) do_something() I tried various WSGI servers, but they have all been giving me concurrency limitations, as in I have to specify how many threads to use and so on. I only wish that the resources on the server be used efficiently and liberally. Any ideas?

  • python script argument misinterpreted in Hudson Execute Shell step

    - by chz
    When I run my python script in the shell terminal, it works sudo myscript.py --version=22 --base=252 --hosts="{'hostA':[1],'hostB':[22]}" But when I run in Hudson and Jenkins, using Execute Shell step, somehow, the string --hosts="{'hostA':[1],'hostB':[22]}" is interpreted as sudo myscript.py --version=22 --base=252 '--hosts="{'hostA':[1],'hostB':[22]}"' How do we overcome this so that our script would run in Jenkins and Hudson ? Thank you. Sincerely

  • Emacs bulk indent for Python

    - by Vernon
    Working with Python in Emacs if I want to add a try/catch to a block of code, I often find that I am having to indent the whole block, line by line. In Emacs, how do you indent the whole block at once. I am not an experienced Emacs user, but just find it is the best tool for working through ssh. I am using Emacs on the command line(Ubuntu), not as a gui, if that makes any difference.

  • [Embedded Python] Invoking a method on an object

    - by jmucchiello
    Given a PyObject* pointing to a python object, how do I invoke one of the object methods? The documentation never gives an example of this: PyObject* obj = .... PyObject* args = Py_BuildValue("(s)", "An arg"); PyObject* method = PyWHATGOESHERE(obj, "foo"); PyObject* ret = PyWHATGOESHERE(obj, method, args); if (!ret) { // check error... } This would be the equivalent of >>> ret = obj.foo("An arg")

  • Writing a file shredder in python or ruby?

    - by pmilb21
    In the effort to learn python and/or ruby, I was wondering how a file shredder would be implemented? I would like it to take in a file as an argument and then employ an algorithm to make that file unrecoverable. Would possibly add the support for multiple files or even whole directories later.

  • python: list manipulation

    - by Jason S
    I have a list L of objects (for what it's worth this is in scons). I would like to create two lists L1 and L2 where L1 is L with an item I1 appended, and L2 is L with an item I2 appended. I would use append but that modifies the original list. How can I do this in Python? (sorry for the beginner question, I don't use the language much, just for scons)

  • [python] parsing a string based on specified identifiers

    - by jml
    Let's say that I have the following text: in = "one aaa two bbbb three cccc" I would like to parse this into a group of variables that contain notworking = ["one", "two", "three"] v1,v2,v3 = in.split(notworking) I know that the example above won't work, but is there some utility in python that would allow me to use this sort of approach? I know what the identifiers will be in advance, so I would think that there has got to be a way to do this... Thanks for any help, jml

  • Amazon API library for Python?

    - by Kevin
    What Python libraries do folks use for querying Amazon product data? (Amazon Associates Web Service - used to be called E-Commerce API, or something along those lines). Based on my research, PyAWS (http://pyaws.sourceforge.net/) seems okay, but still pretty raw (and hasn't been updated in a while). Wondering if there's an obvious canonical library that I'm just missing.

  • Limiting the size of a python dictionary

    - by anthony
    I'd like to work with a dict in python, but limit the number of key/value pairs to X. In other words, if the dict is currently storing X key/value pairs and I perform an insertion, I would like one of the existing pairs to be dropped. It would be nice if it was the least recently inserted/accesses key but that's not completely necessary. If this exists in the standard library please save me some time and point it out!

  • Are classes in Python in different files?

    - by Asaf
    Much like Java (or php), I'm use to seperating the classes to files. Is it the same deal in Python? plus, how should I name the file? Lowercase like classname.py or the same like ClassName.py? Do I need to do something special if I want to create an object from this class or does the fact that it's in the same "project" (netbeans) makes it ok to create an object from it?

  • Python new-style classes and __subclasses__ function

    - by Fraser Graham
    Can somebody explain to me why this works (in Python 2.5) : class Foo(object): pass class Bar(Foo): pass print(Foo.__subclasses__()) but this doesn't : class Foo(): pass class Bar(Foo): pass print(Foo.__subclasses__()) The latter returns "AttributeError: class Foo has no attribute '__subclasses__'" but i'm not sure why. I know this is related to old-style vs. new-style classes but i'm not clear on why that would make this functionality unavailable.

  • Parsing timestamp with retarded Python

    - by jellybean
    I want to parse a timestamp from a log file that has been written via datetime.datetime.now().strftime('%Y%m%d%H%M%S') and then compute the number of seconds that have passed since this timestamp. I know I could do it with datetime.datetime.strptime to get back a datetime object and then compute a timedelta. Problem is, the strptime function has been introduced with Python 2.5 and I'm using Python2.4.4 (an upgrade is not possible in my context). Any easy way to do this?
