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.
What sort of mime type should I be using to email a .avi file from an automated python script? There are specific ones for audio/images, but not video afaik.
What is the most effective and compatible automatic Python obfuscator? What are your experiences with using each?
And before anyone asks why I am obfuscating -- I am doing it simply because I can. Thanks.
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
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!
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?
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.
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?
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).
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 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?
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]
Hi
I am trying to perform a 2d convolution in python using numpy
I have a 2d array as follows with kernel H_r for the rows and H_c for the columns
data = np.zeros((nr, nc), dtype=np.float32)
#fill array with some data here then convolve
for r in range(nr):
data[r,:] = np.convolve(data[r,:], H_r, 'same')
for c in range(nc):
data[:,c] = np.convolve(data[:,c], H_c, 'same')
It does not produce the output that I was expecting, does this code look OK
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,
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 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.
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,

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)
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.
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'm looking for a way in python to find out which type of file system is being used for a given path. I'm wanting to do this in a cross platform way. On linux I could just grab the output of df -T but that won't work on OSX or windows.
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]))
?
I am running a multithreaded application(Python2.7.3) in a Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz. I thought it would be using only one core but using the "top" command I see that the python processes are constantly changing the core no. Enabling "SHOW THREADS" in the top command shows diffrent thread processes working on different cores.
Can anyone please explain this? It is bothering me as I know from theory that multithreading is executed on a single core.
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.
