cin a b c;

Hi,
I'm building a download manager in python for fun, and sometimes the connection to the server is still on but the server doesn't send me data, so read method (of HTTPResponse) block me forever. This happens, for example, when I download from a server, which located outside of my country, that limit the bandwidth to other countries.
How can I set a timeout for the read method (2 minutes for example)?
Thanks, Nir.
I'm looking for a python library that will help me analyze the audio in wav files. At the very least I'm hoping to find some kind of interface that understands .wav format so that I don't have to :P at best I need a module with methods for reading wave form parameters like pitch, volume levels, etc
In need to determine the angle(s) between two n-dimensional vectors in Python. For example, the input can be two lists like the following: [1,2,3,4] and [6,7,8,9].
Can anybody help me? Thanks in advance!
I'm a newbie to regular expressions and I have the following string:
sequence = ["{\"First\":\"Belyuen,NT,0801\",\"Second\":\"Belyuen,NT,0801\"}","{\"First\":\"Larrakeyah,NT,0801\",\"Second\":\"Larrakeyah,NT,0801\"}"]
I am trying to extract the text Belyuen,NT,0801 and Larrakeyah,NT,0801 in python. I have the following code which is not working:
re.search('\:\\"...\\', ''.join(sequence))
I.e. I want to get the string between characters :\ and \.
Hi guys
I'm looking for an equivalent in python of dictionary.get(key, default) for lists. Is there any one liner idiom to get the nth element of a list or a default value if not available?
Thanks!
I have a lot of Perl scripts that looks something like the following. What it does is that it will automatically open any file given as a command line argument and in this case print the content of that file. If no file is given it will instead read from standard input.
while ( <> ) {
print $_;
}
Is there a way to do something similar in Python without having to explicitly open each file?
Hi All
I would like to handle time series in python.
I have been suggested to use scikit.timeseries but I need to handle up to microseconds and this last, as far as I know, handles up to milliseconds.
Do you know any other library able to do that? At some point I need to merge 2 time series sampled at different time, and I would like to avoid rewriting such kind of features or any new classes from scratch whenever it is possible.
I thank you all

Is there any way to have Python operators line "==" and "" return ints instead of bools. I know that I could use the int function (int(1 == 1)) or add 0 ((1 == 1) + 0) but I was wondering if there was an easy way to do it. Like when you want division to return floats you could type from __future__ import division. Is there any way to do this with operators returning ints? Or could I make a class extending __future__._Feature that would do what I want?
Hi, I have mod_python installed on my server, but if I want to acceses a python script - let's say httü://site.com/something.py the script doesn't run, the download box "pops up"
Any solutions?
I am trying to retrieve a 500mb file using Python, and I have a script which uses urllib.urlretrieve(). There seems to some network problem between me and the download site, as this call consistently hangs and fails to complete. However, using wget to retrieve the file tends to work without problems. What is the difference between urlretrieve() and wget that could cause this difference?
I'm looking for a way to programatically control a browser on a Mac (i.e. not IE) using Python.
The actions I need include following links, checking if elements exist in a page, and submitting forms.
Which solution would you recommend?
Thanks!
I'd like to be able to parse out the city, state or zip from a string in python. So, if I entered
Boulder, Co
80303
Boulder, Colorado
Boulder, Co 80303
...
any variation of these it would return the city, state or zip.
This is all going to be user inputted data and inputted in one text field.
Hi,
I'm running a Mac OS X environment and am used to using ~/ to provide the access to the current user's directory.
For example, in my python script I'm just trying to use
os.chdir("/Users/aaron/Desktop/testdir/")
But would like to use
os.chdir("~/Desktop/testdir/")
I'm getting a no such file or directory error when trying to run this. Any ideas?
In a Python Google App Engine app I'm writing, I have an entity stored in the datastore that I need to retrieve, make an exact copy of it (with the exception of the key), and then put this entity back in.
How should I do this? In particular, are there any caveats or tricks I need to be aware of when doing this so that I get a copy of the sort I expect and not something else.
can you convert this perl code to python code :
$list = $ARGV[0];
open (PASSFILE, "$list") || die "[-] Can't open the List of password file !";
@strings = ;
close PASSFILE;
Thanks
Is it possible to set a default value for a variable argument list in Python 3?
Something like:
def do_it(*args=(2, 5, 21)):
pass
I wonder that a variable argument list is of type tuple but no tuple is accepted here.
I am writing a test harness in python and as part of the testing I need to initialise an FTP server and upload various files. I am using ftplib and everything is working ok. The only problem I have is that I am seeing loads of FTP text appearing in the console window intermixed with my test results, which makes scanning the results quite tricky. I haven't found a way to shut ftp lib up and stop this happening, does anyone know how to stop this?
Dear all, I need to implement a TCP server in Python which receives some data from a client and then sends this data to another client. I've tried many different implementations but no way to make it run. Any help would be really appreciated.
I'm trying to do this:
commands = { 'py': 'python %s', 'md': 'markdown "%s" "%s.html"; gnome-open "%s.html"', }
commands['md'] % 'file.md'
But like you see, the commmands['md'] uses the parameter 3 times, but the commands['py'] just use once. How can I repeat the parameter without changing the last line (so, just passing the parameter one time?)
I'm having some issues trying to pull a shared contact using the gdata api for python that Google provides. Here is what I have to get the contacts.. but they are not all listed there

print entry.title
I can't figure out how to pull out a single contact so I can edit the contact information..

How to retrieve the process start time (or uptime) in python in Linux?
