  • Pure python implementation of greenlet API

    - by Tristan
    The greenlet package is used by gevent and eventlet for asynchronous IO. It is written as a C-extension and therefore doesn't work with Jython or IronPython. If performance is of no concern, what is the easiest approach to implementing the greenlet API in pure Python. A simple example: def test1(): print 12 gr2.switch() print 34 def test2(): print 56 gr1.switch() print 78 gr1 = greenlet(test1) gr2 = greenlet(test2) gr1.switch() Should print 12, 56, 34 (and not 78).

  • In google app engine, how to iterate through form fields (python, wsgiref.handlers)

    - by MarcoB
    Using python and wsgiref.handlers, I can get a single variable from a form with self.handler.request.get(var_name), but how do I iterate through all form variables, be they from GET and POST? Is it something like this? for field in self.handler.request.fields: value = self.handler.request.get(field) Again, it should include both fields included in the POST and fields from the query string, as in a GET request. Thanks in advance folks...

  • installing a package with xml based configuration in python

    - by saminny
    Hi, I am planning to write a generic python module for installing a package. This script should retrieve the module from a remote machine or locally and install it on a given host and user. However, there needs to be changes made to the package files based on the host, user and given environment. My approach is to use XML to describe changes to be made to package files based on environment. It will first extract the package to the user directory and then using an xml configuration file, it should replace the file values in the package directory. The xml would look something like this: <package version="1.3.3"> <environment type="prod"> <file dir="d1/d2" name="f1"> <var id="RECV_HOST" value="santo"> <var id="RECV_PORT" value="RECV_PORT_SERVICE" type="service"> <var id="JEPL_SERVICE_NAME" value="val_omgact"> </file> <var dir="d4/d3/s2" name="f2"> <var id="PRECISION" value="true"> <var id="SEND_STATUS_CODE" value="323"> <var id="JEPL_SERVICE_NAME" value="val_omgact"> </file> </environment> <environment type="qa"> <file dir="d1/d2" name="f1"> <var id="RECV_HOST" value="test"> <var id="RECV_PORT" value="1444"> <var id="JEPL_SERVICE_NAME" value="val_tsdd"> </file> <file dir="d4/d3/s2" name="f2"> <var id="PRECISION" value="false"> <var id="SEND_STATUS_CODE" value="323"> <var id="JEPL_SERVICE_NAME" value="val_dsd"> </file> </environment> </package> What are your thoughts on this approach? Is there an existing python module, package or script that I could use for this purpose since this seems fairly generic and can be used for any installation. Thanks! Sam

  • Python process will not exit

    - by oneself
    Hi, I'm use nosetests to run some tests. However, after the tests have finished running, the nosetests process just sits there, and will not exit. Is there anyway to diagnose this? Does Python have a facility similar to sending Java a kill -QUIT which will print a stack trace?

  • python: equivalent to Javascript "||" to override non-truthful value

    - by Jason S
    In Javascript I can do this: function A(x) { return x || 3; } This returns 3 if x is a "non-truthful" value like 0, null, false, and it returns x otherwise. This is useful for empty arguments, e.g. I can do A() and it will evaluate as 3. Does Python have an equivalent? I guess I could make one out of the ternary operator a if b else c but was wondering what people use for this.

  • How does Python store lists internally?

    - by Mike Cooper
    How are lists in python stored internally? Is it an array? A linked list? Something else? Or does the interpreter guess at the right structure for each instance based on length, etc. If the question is implementation dependent, what about the classic CPython?

  • Exposing members or make them private in Python?

    - by deamon
    Is there a general convention about exposing members in Python classes? I know that this is a case of "it depends", but maybe there is a rule of thumb. Private member: class Node: def __init__(self): self.__childs = [] def add_childs(self, *args): self.__childs += args node = Node() node.add_childs("one", "two") Public member: class Node2: def __init__(self): self.childs = [] node2 = Node2() node2.childs += "one", "two"

  • Python: if key in dict vs. try/except

    - by LeeMobile
    I have a question about idioms and readability, and there seems to be a clash of Python philosophies for this particular case: I want to build dictionary A from dictionary B. If a specific key does not exist in B, then do nothing and continue on. Which way is better? try: A["blah"] = B["blah"] except KeyError: pass or if "blah" in B: A["blah"] = B["blah"] "Do and ask for forgiveness" vs. "simplicity and explicitness". Which is better and why?

  • viewing files in python?

    - by Galilsnap
    I am creating a sort of "Command line" in Python. I already added a few functions, such as changing login/password, executing, etc., But is it possible to browse files in the directory that the main file is in with a command/module, or will I have to make the module myself and use the import command? Same thing with changing directories to view, too.
