Let say i want to read the integers a, b and c from stdin (in one line, do not need to press return after each number). In c++, i would just do:
cin a b c;
How to do this in Python ?
I need to count the number of files in a directory using Python.
I guess the easiest way is len(glob.glob('*')), but I also count the directory as file.
Is there any way to count only the files in a directory?
I want to write a database app in Python, using SQLite and wxPython.
My only "experience" is 1 class on basic C++ console programming and OOP concepts.
Which IDE would be best for my situation?
In case it matters, I only need my new program to run on Windows, and I do want to make it "portable".
Thank you.

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.
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?
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
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

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
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?
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 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, 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?
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?
What is the best way to implement the singleton pattern in Python? It seems impossible to declare the constructor private or protected as is normally done with the Singleton pattern...

How to retrieve the process start time (or uptime) in python in Linux?
I only know, I can call "ps -p my_process_id -f" and then parse the output. But it is not cool.
I have a python script that accepts a file from the user and saves it.
Is it possible to not upload the file immediately but to que it up and when the server has less load to upload it then.
Can this be done by transferring the file to the browsers storage area or taking the file from the Harddrive and transferring to the User's RAM?
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?
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?)
When I serialize a list of objects with a custom __get__ method, __get__ is not called and the raw (unprocessed by custom __get__) value from __set__ is used. How does Python's json module iterate over an item?
Note: if I iterate over the list before serializing, the correct value returned by __get__ is used.
