Folks, This is my first Python project so please bear with me. I need to download data from Yahoo Finance in CSV format. The symbols are provided in a text file, and the project details are included below. Does anyone have some sample code that I could adapt? Many thanks in advance, dan

Hi, I'm trying to use the function paste() to paste a image into another image but I can't get it work! Is it the right function to use or is there any other function that's better? Here's my very simple code: from PIL import Image import ImageDraw im = Image.new("RGB", (500,500), "white") draw = ImageDraw.Draw(im)

Hi I'm creating a program in Tkinter and I would need help to create a "close button" for dialog windows. One of my typical dialog windows look like this: def show_window(self): top = Toplevel()

Hi, I am trying to come up with a clean and simple way to sort a list of objects (in this case SQLObject instances) by multiple attributes. e.g. a Person object may have an age, a lastName, and a firstName. I'd like to be able to arbitrarily sort by any combination of those in any order.

Hi, I have the following in a text file: 1,a 1,b 1,b 2,a 2,c 2,a

Hiya, I've got a PIC microcontroller reading me humidity data via rs232, this is in ASCII format. I can view this data easily using hyperterminal or pyserial and convert it to its value (relative humidty with ord(input)) But what im trying to do is plot the data in real time, ideally with pylab - as it looks simple to use and simple is...

In a nutshell - the question I'm asking is, how do I make a socket conenction go via a proxy server ? All our internet traffic has to go through a proxy-server at location 'dav-serv:8080' and I need to make a socket connection through it. The reason (with code example) is as follows : I am hacking "Tiny HTTP Proxy" by SUZUKI Hisao to make...

Hi, I have a small test to "compile" al litle script as a WMI-Tester. The script include a wmi-wrapper and "insert" the Win32-modeles. here the code: my "WMI-Tester.py" ----- import wmi

I've got a grid-managed frame, containing a column of Labels, and a corresponding column of Entry widgets. I'd like to be able to display dozens, or even hundreds of rows, and use a vertical scrollbar to scroll through them in the frame. So far i can get a scrollbar to display, but it won't scroll anything. So that's definately wrong. And the...

I'm using the os.system command in a python script on Windows to run a batch file like this: os.system('x.exe') The third-party program x.exe outputs some text to the console that I want to prevent from being displayed. Is there a way to prevent the output of x.exe from python?

Hi, I have some PHP scripts I'm moving from my web server to the local PC. They just do file manipulation. Anybody know of a tool for translating PHP to Python? A partial translation would be hwlpful. Also, any tips or pritfalls to look out for?

Hey Guys. I'm looking for some info on how to read binary image data. Basicly RAW image files are strings of bits with say 2 bytes per pixel. What i need to do is read the value of each pixel in turn and store then in another variable, px1, pix2 etc. I'm running an iterative algorithm on 2 pixels at a time then moving to the next two pixels. I...

I'm sure this is a very simple thing to do, once you know how to do it, but I am having no fun at all trying to write utf-8 strings to a unicode file. Does anyone have a couple of lines of code that - opens a file appropriately for output - writes to this file Thanks very much. Michael Weir

Can I get reference to module object of current module (from which the code is currently executed)? I know __import__('filename') should probably do that, but the call contains redundant information (filename, which needs to be updated), and it'll perform unnecessary search in loaded modules list. It shouldn't be a real problem (filename...

Hi, Is there a way to force a specific parameter in a function to be a specific type? For example, say the first parameter in a function of mine is required to be a string. If the user passes in an integer, I want to notify them that they should pass in a string, not an integer.

if(re.match("(^|^{0,1}{1,2})\.(|{0,1}{1,2})\.(|{0,1}{1,2})\.(|{0,1}{1,2})$",ip_addr) != None): print "Verified as passed" else: print "Verified as failed"

Is there a function that takes a number with binary numeral a1...an to the number with binary numeral b1...bn, where each bi is 1 if ai is 0, and vice versa? (For example, the function's value at 18 would be 13 .) I thought this was what the tilde operator (~) did, but when I went to try it I found out that wasn't the case. I discovered by...

Let's say I have this Python file called loop.py: import sys print 'hi' sys.stdout.flush() while 1: pass And I want to call it from another Python process and read the value 'hi'. How would I do it?

Hi, When I do a small program like from subprocess import Popen popen = Popen() from time import sleep sleep(100) start it and kill it, the ping process lives on. Is there a way to ensure that the ping process is always killed when the python process is?

Hi, I am a real beginner in Python and I was wondering if there is a way to convert a string (which contains a list) to a "real" list. I need this since I would like to give a list as an argument to my Python script from the bash: #!/usr/bin/python import sys

hi everyone, I'm googeling since some time, but can't find an answer - maybe because the answer is 'No!'. Can I call a function in python inline, so that the python byte compiler does actually call the function, but sort of inserts it where the inline call is made? Therefore avoiding the function all overhead. Thanks and cheers,

I see this set (or similar) of variables in various modules I read. They are found near the top of each module file, outside of any class or function definitions. " __author__ = "Software Authors Name" __copyright__ = "Copyright (C) 2004 Author Name" __license__ = "Public Domain" __version__ = "1.0" "

In the context of LATEX, some Pythonista asked what the big successes of Lisp were. I think there were at least three *big* successes. a. orbitz.com web site uses Lisp for algorithms, etc. b. Yahoo store was originally written in Lisp. c. Emacs The issues with these will probably come up, so I might as well mention them myself (which...

Hi, What is the difference between: 1) getting the returncode directly from the subprocess object 2) calling poll() on the subprocess object? Here is an example:
