Now that I use python, this is the amount of time per day that I spend adding forgotten semicolons while debugging other languages.

[ANN] argparse 1.1 - Command-line parsing library
by Steven Bethard March 1, 2010

March 1, 2010

======================= Announcing argparse 1.1 ======================= The argparse module provides an easy, declarative interface for creating command line tools, which knows how to: * parse the arguments and flags from sys.argv * convert arg strings into objects for your program * format and print informative help messages * and much more... The argparse module improves on the standard library optparse module in a number of ways including: * handling positional arguments * supporting sub-commands * allowing alternative option prefixes like + and / * handling zero-or-more and one-or-more style arguments * producing more informative usage messages * providing a much simpler interface for custom types and actions Download argparse ================= The argparse homepage has links for source, MSI and single file distributions of argparse: http://code.google.com/p/argparse/ About this release ================== This is the final release of argparse before its move to the Python 2.7 and 3.2 standard libraries. Major enhancements in this release: * ArgumentParser(..., version=XXX) is deprecated. Instead, you should use add_argument(..., action='version') which is more flexible and does not force you to accept -v/--version as your version flags. * Usage and help (but not version) messages are now written to stdout instead of stderr, consistent with most existing programs. * User defined types passed as a type= argument can now raise an ArgumentTypeError to provide a custom error message. * Namespace objects now support containment, e.g. "'foo' in args". Various bugs were also squashed, e.g. "from argparse import *" now works. See the news file for detailed information: http://argparse.googlecode.com/svn/tags/r11/NEWS.txt Enjoy!

Stefan, I was happy to see such concise code. Your python worked with only very minor modifications. Hai's test xml data *without* the first and last line is close enough to the data I am using: <order customer="john" product="eggs" quantity="12" /> <order customer="cindy" product="bread" quantity="1" /> <order customer="larry" product="tea bags" quantity="100" /> <order customer="john" product="butter" quantity="1" /> <order product="chicken" quantity="2" customer="derek" /> ... quirky. I get a large file given to me in this format. I believe it is created by something like: grep 'customer=' *.xml, where there are a large number of xml files. I had to edit the data to include the first and last lines, <orders> and </orders>, to get the python code to work. It's not an arduous task(!), but can you recommend a way to get it to work without manually editing the data? One other thing, what's the Roland Mueller post above about (I'm viewing htis in google groups)? What would the test.xsl file look like? Thanks again Hal.

Starting Python from the terminal with no welcome message
by candide March 1, 2010

March 1, 2010

Hi, Does exist some option I could send to the python interpreter during an interactive session in order to avoid the printing of the introductory message just above the top prompt ? In my case, the welcome message is the following : Python 2.5.2 (r252:60911, Jul 31 2008, 17:28:52) [GCC 4.2.3 (Ubuntu 4.2.3-2ubuntu7)] on linux2 Type "help", "copyright", "credits" or "license" for more information. gdb has such an option (the so-called quiet option). Compare this : $ gdb GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.

Multiple console windows for a single program?
by Blake B March 1, 2010

March 1, 2010

Hello, I'm wanting to write a program with multiple objects, each in a thread. Both will be doing output (with the print statement) almost constantly, so I'd like to be able to separate their outputs. What I want to do is have a separate window for each. Is my only option to make my own "console" windows using TK or something? Thanks in advance, Blake B
