in os module there is many funktion/methods to extract this information to ask the path to the current running pythonprogram you can do likes this ----- CUT----------- import os print os.getcwd() ----- CUT ------ // Anders Michael Malinowski skrev: > Is there a way to read the directory that the currently running python file > is located in? > Cheers > Mike.

Re: Python Question About Compiling.

I can see the point of people who are confused about single file executables for Python programs, who are possibly new to the technology and don't know where to look [1] or which questions to ask, and I can also see the need in various situations for people to make such executables. That said, I don't buy into the kind of hypothetical "ISVs need this and that" pontification seen on places like Planet GNOME, written by people who work at companies like Novell. The "commercial circuit" will use a technology (and, in fact, have been using Python for some time) when they recognise the genuine benefits of the technology, and if the technology doesn't deliver exactly what they had in mind, they'll either put in some effort to shape it to their liking or they'll look elsewhere. If none of this activity has any community benefit, I'd argue that there's only so much the community should be prepared to do to "fix" such commercial objections - if what a business wants is valuable enough, that business should be prepared to pay for it. > (why are you blaming you inability to use Linux installation tools on > Python, btw? most basic Python libraries are only an apt-get away if > you're using a sane Linux distribution.) This is true enough, and by packaging one's programs correctly, Python gets automatically brought into the picture when the user asks to install those programs. It's interesting to consider this in the context of the recent Linux Standard Base discussions on python-dev: LSB potentially mitigates issues with shipping executables across different distributions and would be beneficial to those wanting to deploy Python applications in such a way. I notice, however, that the discussion has taken the peanut gallery position of name-calling and mock outrage at the packaging practices of various distributions [2], presumably whilst advocating Python-only solutions like setuptools - something which really isn't going to work well with any large heterogeneous collection of software packages. Moreover, the distributions have to more urgently deal with various issues not yet sufficiently addressed by the Python core developers, particularly architecture issues [3] and licensing issues [4]. Freezing applications has been a fairly well-understood process for the last ten years, but more cooperation with heterogeneous packaging technologies would be far preferable. After all, distributions are actually responsible for a large amount of Python usage, and it would be far better if people actually tried to work with them to resolve some of the supposedly inflammatory aspects of their packaging practices rather than just shouting bad things at them from a distance [5]. A bit of "not invented here" [6] suppression would also be quite welcome, along with taking the needs of vendors [7] other than Apple Computer Inc. into account. Paul P.S. And while a frank discussion [7] did appear to result in a comprehensive exchange of views between Debian and setuptools developers, I'd like to see a bit more understanding for end-users and people who don't want to ignore their system's package management. Python "plays well with others" is a frequent claim, after all.

I personally tried eclipse on my laptop (which I work most with), and I had quite a system resource problem. So I switched back to vim and console and it hasn't been too bad, since if you know how to use a powerful editor, it can be as productive. But in the end, it is up to anyone to find the best solutiion for themselves. Thomas

I don't know about raw_input ... my programs all go through some GUI ... but I run / debug(although almost never) all of my applications from pydev - no need to change project as with Visual Studio, I just run/debug whatever I need with a few clicks ... have not touched Konsole in weeks. I also, after weeks of testing, decided to invest in the pydev extensions / the bugs it has found for me already justify the investment. hg

Win32 Excel Generation Slow
by Daniel Bowett Dec. 1, 2006

Dec. 1, 2006

I am trying to create an excel document that displays a table of data. It does exactly what I want but takes a long time. I am writing around 1000 rows and it takes around a second to do each row. Is there a quicker way to write this? The reason I want excel is this needs to read and manipulated by management. The function I am using is: def createExcel(data): xlApp = Dispatch("Excel.Application") wb = xlApp.Workbooks.Add() xlApp.Visible = 1 ws = wb.Worksheets[0]; headers = ["Sales Rank", "UPC", "Description", "Stock", "Manifest Stock", "Total Stock", "Week Sales", "Price", "Total Price", "Days Cover"] column = 1 for each in headers: xlApp.ActiveSheet.Cells(1, column).Value = each column = column + 1 row = 1 for eachline in data: xlApp.ActiveSheet.Cells(row, 1).Value = row xlApp.ActiveSheet.Cells(row, 2).Value = eachline[0] xlApp.ActiveSheet.Cells(row, 3).Value = eachline[1] xlApp.ActiveSheet.Cells(row, 4).Value = eachline[2] xlApp.ActiveSheet.Cells(row, 5).Value = eachline[3] xlApp.ActiveSheet.Cells(row, 6).Value = eachline[4] xlApp.ActiveSheet.Cells(row, 7).Value = eachline[5] xlApp.ActiveSheet.Cells(row, 8).Value = eachline[6] xlApp.ActiveSheet.Cells(row, 9).Value = eachline[7] xlApp.ActiveSheet.Cells(row, 10).Value = eachline[8] row = row + 1

Surprise with special floating point values
by prouleau001＠gmail.com Dec. 1, 2006

Dec. 1, 2006

Hi all, While trying to use simplejson under Python 2.4.3 I have been investigating the handling of special floating point values and found that both Python 2.4 and 2.5 return False when comparing a NaN with itself. Although surprising, I imagine it could also be correct since NaN is not a number. But is it correct? Notice the result of comparing c with itself in the following Python 2.5 session (it works the same on Python 2.4.3) under Win32:: Python 2.5 (r25:51908, Sep 19 2006, 09:52:17) [MSC v.1310 32 bit (Intel)] on win32 Type "help", "copyright", "credits" or "license" for more information. >>> a = 1e300 * 1e300 >>> a 1.#INF >>> b = 1e66666 >>> b 1.#INF >>> a == b True >>> c = a - a >>> c -1.#IND >>> d = b - b >>> d -1.#IND >>> c == d False >>> c == c False >>> b == b True >>> a == a True >>> a is a True >>> b is b True >>> c is c True >>> d is d True >>> Thanks, -- Pierre Rouleau

Distutils questions.
by José Rui Faustino de Sousa Dec. 1, 2006

Dec. 1, 2006

Hi! I am writing a package installation using distutils it is very nice but I have it two snags: setup(... data_files=[("foo",["*.data""])],\ ...) setup.py install --prefix=/usr/bar/baz a) Shouldn't the *.data syntax work? b) Why does it install the data files on /usr/bar/baz/foo and not in /usr/bar/baz/share/foo like the documentation seems to imply? Everything else seems to work as advertised scripts go to <prefix>/bin packages to <prefix>/lib/python2.4/site-packages... Is it me or is it a bug? Best regards José Rui

python 2.5 install from source problem
by Fabian Braennstroem Dec. 1, 2006

Dec. 1, 2006

Hi, I just tried to install python 2.5 from source on my ScienticLinux (Redhat Clone) machine. It seems to work without any problem, at least I am able to run some of my old scripts. I installed it with './configure --prefix=/opt/python make make altinstall', but now for a 'vtk' installation which needs the python libraries I am not able to find a file like 'libpython2.5.so.*', which I think should be produced (at least at my office's machine (redhat) it is there). I just can find a 'libpython2.5.a' file ... Do I do something wrong? Greetings! Fabian
