Hello everyone,
How can I get the file name and line number in python script.
Exactly the file information we get from an exception traceback. In this case without raising an exception.
Hi, I'm developing C extensions from python ad I obtain some segfaults (inevitable during the development...).
I'm searching a way to display at which line of code the segfault happens (an idea is like tracing every single line of code), how I can do that?
Hey, here's a dumb question: how can I set an object property given its name in a string. I have a dictionary being passed to me and I wish to transfer its values into namesake properties using code like this:
for entry in src_dict:
if entry.startswith('can_'):
tgt_obj[entry] = src_dict_profile[entry]
I'm still a bit of a noob with Python so would appreciate some help.

I have a few questions about python
I've seen many pages like these on Google
http://mail.google.com/support/bin/answer.py?answer=6583
https://www.google.com/adsense/support/bin/topic.py?topic=13488
...that have .py extensions. 1: Are pages like these built on pure python code, but printing out html like print "<div etc..." or like the typical asp,jsp,php type of pages with html pages and embedded python code like:
<html>
<% some python code %>
</html>
2: What is python mainly used for making? windows apps or web or .. ?
3: Are ruby and perl also similar to python?
I have written a simple python module, it has this code:
_log = logging.getLogger("mymodule")
_started = False
def set_log_level(level):
_log.setLevel(level)
if not _started:
_hdlr = logging.FileHandler('mymodule.log')
When I call set_log_level() program fails because symbol _started is not found. It is normal because global _started is missing in the method. But my question is: symbol _log has the same visibility as _started, so why does this symbol can be found?

I am building a python application to pull data from a website. The application has to authenticate(HTTPS/SSL) with a CAC card and pin in order to make requests.
Am I correct in my assumptions that you can't retrieve the private key from a CAC card, and am therefore stuck using a PKCS #11 Wrapper like PyKCS?
Any tips or resources for going about this?
Hi there,
I have a piece of text that gets handed to me like:
here is line one\n\nhere is line two\n\nhere is line three
What I would like to do is break this string up into three separate variables.
I'm not quite sure how one would go about accomplishing this in python.
Thanks for any help,

How can I parse text and find all instances of hyperlinks with a string? The hyperlink will not be in the html format of <a href="http://test.com">test</a> but just http://test.com
Secondly, I would like to then convert the original string and replace all instances of hyperlinks into clickable html hyperlinks.
I found an example in this thread:
Easiest way to convert a URL to a hyperlink in a C# string?
but was unable to reproduce it in python :(
I write a python class which makes asynchronous method calls using D-Bus. When my reply_handler is called, it stores data in list. This list can be used by another class methods at the same time. Is it safe or I can use only synchronized data structures like Queue class?
I was working with Python with a Linux terminal screen. When I typed:
help(somefunction)
It printed the appropriate output, but then my screen was stuck, and at the bottom of the terminal was "(end)".
How do I get unstuck? Thanks in advance.
What's the best way of getting the last item from an iterator in Python 2.6? For example, say
my_iter = iter(range(5))
What is the shortest-code / cleanest way of getting 4 from my_iter?
I could do this, but it doesn't seem very efficient:
[x for x in my_iter][-1]
I am trying to get the response codes from Mechanize in python. While I am able to get a 200 status code anything else isn't returned (404 throws and exception and 30x is ignored). Is there a way to get the original status code?
Thanks
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...
Format is like:
CHINA;2002-06-25 00:00:00.000;5,60
CHINA;2002-06-26 00:00:00.000;5,32
CHINA;2002-06-27 00:00:00.000;5,31
and I try to use Python's CSV tools to parse it but cannot understand the paragraph, source:
And while the module doesn’t directly support parsing strings, it can easily be done:
import csv
for row in csv.reader(['one,two,three']):
print row
Could someone clarify the line ['one,two,three']? How would you use it with format A;B;C?
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!

I have a text document that contains a list of numbers and I want to convert it to a list. Right now I can only get the entire list in the 0th entry of the list, but I want each number to be an element of a list. Does anyone know of an easy way to do this in Python?
1000
2000
3000
4000
to
['1000','2000','3000','4000']
Hi,
Fastest way to uniqify a list in Python without preserving order? I saw many complicated solutions on Internet - could they be faster then simply:
list(set([a,b,c,a]))
?
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).
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?
I am creating an application that lets users login using Google, Facebook and the website's native login. The site is being built in Python / Django.
What would be the best way to handle login, session management and user authentication?
I do not want to use the in-built Django user management. I am using Django very sparingly(URLs, templates)
I downloaded a webpage in my python script.
In most cases, this works fine.
However, this one had a response header: GZIP encoding, and when I tried to print the source code of this web page, it had all symbols in my putty.
How do decode this to regular text?
Hello everyone, i'm looking for a way in python to run an external binary and watch it's output for: "up to date" If "up to date" isn't returned i want to run the original command again, once "up to date" is displayed i would like to be able to run another script. So far I've figured out how to run the binary with options using subprocess but thats as far as I've gotten. Thanks!
how can I use wild cars like '*' when getting a list of files inside a directory in Python? for example, I want something like:
os.listdir('foo/*bar*/*.txt')
which would return a list of all the files ending in .txt in directories that have bar in their name inside of the foo parent directory.
how can I do this?
thanks.
I wrote PyQt application. After it's start I close it (GUI), but timer don't stops and Python sometimes freezes. Only thing to unfreeze it - Ctrl-C, after which following message appears:
Traceback (most recent call last):
File "", line 262, in timerEvent
KeyboardInterrupt
timer don't stops again, and CPython works very slowly. How to avoid this problem?
