Using Numeric 24.0b2 with Scientific.IO.NetCDF
by bandw June 30, 2005

June 30, 2005

I am having a problem using Numeric-24.0b2 in conjunction with the NetCDF module from ScientificPython (version 2.4.9). This problem does not surface using Numeric-23.8. The problem arises in using the "min" function on a NetCDF floating array. In 23.8, the "min" function returns a floating scalar, while in 24.0b2 it returns an *array* of length "1". Below I list a simple NetCDF file and a Python script that illustrate the problem. When I run the script using 23.8, I get the result: 1.0 <type 'float'> whereas using 24.0b2 I get: 1.0 <type 'array'> This creates a backward incompatibility that breaks several of my codes. NetCDF file simple.cdl (used to create simple.nc with "ncgen") -------------------------------------------------------------- netcdf simple { dimensions: num = 3 ; variables: float temp(num) ; data: temp = 1, 2, 3 ; } Python script ------------- import Numeric from Scientific.IO.NetCDF import NetCDFFile cdf_file1 = NetCDFFile("simple.nc","r") temp = cdf_file1.variables["temp"][:] print min(temp), type(min(temp))

Nick Mountford a écrit : > Hi, > > Complete newb to Python and programming, looking for an open source > IDE to download. Any suggestions? Use something simple. Start with Idle (it comes with Python, and has all the basic features you may need to learn Python). When you'll have learn the bases, it will be time to move to something else.

I feel obliged to point out that there's probably only about 50,000 speakers of Strine in Australia out of approx 20 million people, so a lot of those consonants are ending up in landfill somewhere, rather than being conserved in an environmentally-friendly way. Even people such as myself with a fairly broad country accent (city people sound so wussy ;) don't do our part for conservation of consonants :( Tim Delaney

Hi, In perl I can do something like: $a = 'test string'; $a =~ /test (\w+)/; $b = $1; print $b . "\n"; and my output would be "string". How might this snippet be written in python? Thanks to all...

Python syntax high-lighting and preservation on web
by Gregory Piñero June 30, 2005

June 30, 2005

Hey guys, Does anyone know where I can pick up a style sheet (css) and/or other files/programs I might need to display python code on my website with tab preservation(or replace with spaces) and colored syntax? I want something similar to the python code on a page like this: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/303770 (I think this is a python-list question although maybe it belongs in a css group?) I figure some of you guys would have experience with this. ----- Giving this issue some more thought, I suppose I could make or find a css file anywhere that would work. The hard part would be getting all of the div and class tags added to my python code. So I think what I really need is a program that will do that, or advice on how to begin writing such a program. (It might make a good wordpress plugin too) Thanks, ' Greg

How about integrating distutils and PyPI, so that distutils can automatically download and install packages that are required by the package it's currently installing? In other words, C-Python-AN. <mike -- Mike Meyer <mwm(a)mired.org> http://www.mired.org/home/mwm/ Independent WWW/Perforce/FreeBSD/Unix consultant, email for more information.

Je connais mal python et n'est pas trop le temps de m'y plonger bien que cela semble être assez puissant... import sys import ixio import os M = ixio.getMAC("eth0") S = "%08X %08X" % (M[0] | M[1]<<8 | M[2]<<16 | M[3]<<24, M[4] | M[5]<<8) K = "Errorin:" if len(sys.argv) <> 3: print "Usage %s <src-file> <dst-file>" % sys.argv[0] else: I = open(sys.argv[1],"rb")#ouverture de tpsd.pre avec le flag rb pour read in binary mode O = open(sys.argv[2],"wb") while 1: blk = I.read(1<<13) try: i = blk.index(K) blk = "%sErrorin:%s%s" \ % (blk[:i],S,blk[i+len(K)+len(S):]) O.write(blk) except ValueError: O.write(blk) if len(blk)<1<<13: break O.close() I.close() Voici l'erreur que j'obtiens en essayant d'exécuter ce script: AttributeError: 'string' object has no attribute 'index' D'après moi, index est une méthode de la classe string et non un attribut...Je ne comprend donc pas... Enfin, je précise que je suis malheureusement en version 1.5 de python... :( Autre question: 1<<13 est censé être une taille en octet: comment cela se lit-t-il? Merci d'avance de m'aclairer sur cette erreur et cette question.

building 2.4.1 on HPUX
by Richard Patterson June 30, 2005

June 30, 2005

I'm trying to compile python 2.4.1, on HPUX10.20, with support for tk and tcl 8.4 (installed in /opt/tk and /opt/tcl). I assume this means I need to compile the tkinter module too.. I was getting make errors, saying it couldn't find tcl/tk libs or headers... so I changed the setup.py script, hard coding library and include paths for tcl/tk, but it still didn't build the _tkinter module. So next I modified the Modules/Setup file, uncommenting, and changing compiler arguments to point to the correct lib and include paths. At least it built this time... so I ran make test, and got the following error for test_tcl: TclError: Can't find a usable tk.tcl in the following directories: /opt/tcl8.4.4/lib/tk8.4 <etc .... the rest of the dirs listed are in my home directory> On my system, /opt/tk is a link to /opt/tk8.4.4, therefore, the tk.tcl file is really in /opt/tk/lib/tk8.4/tk.tcl, but why didn't it look there? I'm stumped. Did I really have to hack the setup.py and Setup files? Where is it getting its paths from? Is my environment wrong, or do I need to change some configure parameters? I'm hoping someone out there knows what I'm doing wrong, or perhaps can point me in the right direction. Thanks again Rich
