Re: [Tutor] using easy_install to download eggs
Hi, thanks for the hint. pip (http://pypi.python.org/pypi/pip/) is a drop-in replacement for the easy_install tool and can do that. Just run easy_install pip and set an environment variable PIP_DOWNLOAD_CACHE to the path you want pip to store the files. Note that the cache won't work with dependencies that checkout from a source code repository (like svn/git/hg/bzr). I tried this. It saves the downloaded packages in a form of: http%3A%2F%2Fpypi.python.org%2Fpackages%2Fsource%2FB%2FBareNecessities% 2FBareNecessities-0.2.2.tar.gz.content-type http%3A%2F%2Fpypi.python.org%2Fpackages%2Fsource%2FB%2FBareNecessities% 2FBareNecessities-0.2.2.tar.gz I was looking for *.egs or *.exe pachages.

[Tutor] using easy_install to download eggs
Hello, I would like to use easy_install to cache packages registered at PyPi locally. How can I do this for packages? I tried the hints from: http://peak.telecommunity.com/DevCenter/EasyInstall#installing-on-un-networked-machines It worked for some packages. But for others, the command easy_install -zxad. mercurial just creates a subdirectory and not an *.egg file.

Hi! is there any function/module that allows me to open a directory in the default file manager of a operating system? On Windows you can use os.startfile(). On pure Unices there's no such thing as filetype associations However, if you use a desktop environment, you can spawn xdg-open (from xdg-utils) from Python. This will autodetect gnome, kde and xfce and use their tools (gnome-open, kfmclient, exo-open). I think on OS X/Darwin there's a similar utility called `open'. You can use sys.platform to determine which system you're running on. I wasn't able to start explorer with os.startfile() I then used subprocess.call(['explorer', my_directory]) And it works.

Re: [Tutor] setting program configuration for all files and modules ofa program
Another option is to have the config settiongs in a normal
Python module and just import it.
I think that the cfg-files are much more readable for others.
More readable than:
# Section Heading
variable = value
It looks pretty easy to read to me! :-)
If its very complex you can use dictionaries:
SectionFoo = {
firstName : theValue
second : anotherValue
}
Which is still pretty easy for the casual reader/maintainer
and allows access like:
import myconfig
foo2 = myconfig.SectionFoo['second']
This seems like reinventing what the ConfigParser mdoule [1] already does.
I think I will read the config file once and the provide the parameters
with a settings.py module throughout the program and the modules.
Sounds like doing it twice.
But to my optinion Config Parser offers the following advantage:
- Readable
- All are strings = no strange 'mysetting' is needed.

Re: [Tutor] cut all decimal places with zeros

No.

[Tutor] setting program configuration for all files and modules of a program
Hello,
I am building a simple GUI for a calculation program. I am using config
files (*.cfg) and reading them in with ConfigParser. This works well
because I have nearly all code in 1 text file.
But I would like to modularize my code and separate the GUI code from
the functional code that provides the calculation operations. This will
help to expand the functionality at a later stage. I want to achieve
this through splitting the code into different modules.
The problem is now that I would always have to write the configration
file specific code in each module that uses the configration settings
(see code below).
How can I provide the settings stored in the configuration file
throughout my program to all functions without needing to initiate the
ConfigParser object in each module?
I through of having a special module settings.py which I could use to
read in the configuration from the file and then import this in each module.
Is there a more decent and elegant way?
What is the state of the art in storing and parsing configuraions in
python programs?
Kind regards,
Timmie
# CODE #
import sys
import locale
import ConfigParser
import gettext
## Path to configuration file

[Tutor] cut all decimal places with zeros
Hello,
how can I suppress the decimal places for (only those) numbers whos
decimal places are zero (0)?
Example:
CODE
In [1]: m = 2.0
In [2]: n = 2.56789080
In [3]: n_format = '%.4f' %n
In [4]: n_format
Out[4]: '2.5679'
In [5]: m_format = '%.4f' %m
In [6]: m_format
Out[6]: '2.'
### END
I would like to have the m_format to be formatted like 2 and the
n_format like 2.5679. How can I achive this?
A g with 2.4 should return 2.4 and not 2.4000.
Basically, I am looking for a way to eliminate the decimal places that
are zero (0).
I tried this humble function before appling the formatting and it works
well with the numbers:
### CODE ###
def cut_decimals(float):
input: floating number
output: number as string with zero decimals removed
#print float-int(float)
#print '%.4f' %float
if float-int(float) != 0:
number = '%.4f' %float
number = number.replace('0.','X.')
number = number.replace('0','')
number = number.replace('X.','0.')
else:
number = '%.0f' %float
return number
n = 2.0
m = 2.5678908
g = 2.4
h = 1.45
i = 0.67
numbers = [n, m, g, h, i]
for i in numbers:
i_f = cut_decimals(i)
print i_f
### END ###
### OUTPUT ###
%run ./test_number.py
2
2.5679
2.4
1.45
0.67
### END ###
Is there any more efficient solution using string formatting only?
Thanks in adavance.

[Tutor] loading modules only when needed and PEP 008
Hello fellow Pythonistas, I have a question concerning import statements. My code uses matplotlib to plot the results of my calculations. Since I want to make this plotting functionality a optional feature I would like to import matplotlib only when needed because it takes a lot of time for a TKinter-GUI to start up. And this start-up time is even longer when matplotlib is imported. I am still in doubt because PEP 008 [1] states that all imports should come right at the beginning of the code. My current code goes something like: import sys import matplotlib ## ## do some calcs ## ... matplotlib.plot(mydata) a optimized version would be: import sys plot_data = 'yes' # option: yes/no if plot_data == 'yes': import matplotlib else: pass ## ## do some calcs ## ... if plot_data == 'yes': matplotlib.plot(mydata) else: pass How would you handle such a case?

Re: [Tutor] loading modules only when needed and PEP 008
When I do this sort of thing I like to move my imports into my functions/methods. Would this then be compliant with the style recommendations? The 'main' code then conditionally calls the function/method. All the code in the function safely assumes that the import has been done but code in the calling function assumes the import hasn't been done. Yes, this should a the solution. And as we are talking about style, note that your else: pass isn't really necessary but it does make it explicitly clear that you are choosing not to do anything if the plot_data isn't 'yes'. Ok, so I already got some style here, at least... Are those tabs you're using? Four spaces are preferred, according to the style guide. I always use 4 spaces. This sometimes leads to confusions when working with the same editor on text files that rely tabs but this is another issue... Thanks very much for your fast response!

Re: [Tutor] reading parts of a input string into different variables based on units.
Hello, thank you for the fast reply! A regex would avoid that since it would detect an m as being diffrent to a cm or mm. Of course you will have to work out the right regex but that shouldn't be too difficult if you are sure you have a whitespace separator and a number followed by the unit string. I will see whether I can get the right regex together. Ease for educated computer scientist but for me coming from a Non-Programmer background the rege still bears some fear... and a learning curve. Now you have a list of values for each unit, you just need to convert the string values to numeric and sum them or whatever else you need to do.

split = raw.split('°')
UnicodeDecodeError: 'ascii' codec can't decode byte 0xb0 in position 0: ordinal
not in range(128)
Therefore my question:
* How can I split at the ° without getting a charater encoding error?
* How do I have to encode the °-symbol that it gets correctly displayed in the
Easygui msgbox at line 6?
Thanks inadvance for answering,
Timmie

Re: [Tutor] symbol encoding and processing problem
How do you get this output? The print is after the statement causing the traceback. Are you showing the same code as you ran? Yes. I created this file in PythonWin and run it with IPython. It displays correctly for me (on MacOS X). Are you sure your source is actually encoded in utf-8? Not really. The thing is that I am exchanging my files from Linux (Ubuntu with UTF-8 default) to Windows. What platform are you on? Yesterday I run the code on windows. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] input file encoding
Not sure what you mean by standard encoding (is this an Ubuntu thing?) but essentially whenever you're pulling stuff into Python As it was lined out by others I was printing to a linux terminal which had the encoding set to UTF-8. Therefore and for further processing of the data I had to open it with the right encoding. In this case, assuming you have files in iso-8859-1, something like this: code import codecs filenames = ['a.txt', 'b.txt', 'c.txt'] for filename in filenames: f = codecs.open (filename, encoding=iso-8859-1) This piece of code did the trick. After a short adaption I had exactly what I wanted to achive. Thanks you for your help. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] input file encoding
Hello, I want to process some files encoded in latin-1 (iso-8859-1) in my python script that I write on Ubuntu which has UTF-8 as standard encoding. When I use the print lines_in_myfile is get some wired symbols. How shold I read those files in or convert their encoding to utf-8?

Re: [Tutor] Python Book Recommendations [Was:[Re: Security]]
Hello, Univ of Toronto, Indiana Univ, and Caltech. Dr. Wilson wrote about it in the magazine of Sigma Xi: http://www.americanscientist.org/template/AssetDetail/assetid/48548 It has moved around a lot. It's current official home is on scipy.org: http://www.swc.scipy.org/ There are several links to older SWC URLs on python.org. None of them are in the wiki where they could be easily fixed, however. Chris, THANK YOU, especially for the link, http://www.swc.scipy.org/. My thanks also to Alan, Wesley, and bhaaluu. What a great list Tutor is! Me too, I want to second Dick Moore and thank y'all for sending this out! How nice that the SWC gets updated and improved! @Dick, as another noob, I wish you success in stepping into Python ;-) ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Python Book Recommendations [Was:[Re: Security]]
Hey bhaaluu and list, Have you seen this site yet? http://osl.iu.edu/~lums/swc/ Many many thanks for this link. Although it should be the most obvious to head to the source (python.org) I didn't go there. The above mentioned tutorial seem to cover exactly what I need and where I want do dig deeper it gives valuable references and links for futher readings. I'd recommend this to any non-programmer who likes to learn python to solve his real-life computer problems that arise in his/her science field of origin like earth/geo science, biology, physics or engineering. Once I will have finished this tutorial I may decide whether I by another book or not. Another site that seems really helpful for scientists wanting to learn Python is: http://www.pasteur.fr/formation/infobio/python/ This one had already been mentioned on this thread, I guess.

Re: [Tutor] Python Book Recommendations [Was:[Re: Security]]
Hello list, thanks to everybody who shared their experience with books and their usefulness. I think with regard to the other thread that passed lately: Books with exercises and problems to solve - http://article.gmane.org/gmane.comp.python.tutor/42394 we must admit there are two type of learners: * real programming beginners/novices who take Python to enter the world of programmin or need to program only to solve some specific problems that are arising in other areas of work like scientific data analysis, modelling or engineering * computer professionals who are very familiar with programming and already know some lingos. They need a different learning approach than the first group. I for instance belong to the first group. I need Python for effective data manipulation analysis or program customatization/scripting within other programs, etc. I bought Python Scripting for Comuptional Science by H. Langtangen. While this book adresses exctly my needs as far as the content and spcialization is concerned I want to start off learning with a book that helps me to pick up easier. Learning -- which is a auto-learning and free choice in my case -- should be fun! Therefore I am consindering to buy Python Programming for the Absolute Beginner. Did anyone here use this book for leaning? Is it easy enough for a non-programmer while not being too light? Kind regards, Tim ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

Re: [Tutor] adapting a converter openoffice
When you say nothing happemed I assume you mean the script never terminated? Yes, you are right. it does not terminate and only blocks the screen. As stated on the site the script needs some special parameters of Openoffice. Therefore, until I step further, I wrap it around a shell script that I will put in my PATH: #!/bin/bash ###licence ##which licence applies for this script?

[Tutor] adapting a converter openoffice
Hello,
I am Python learning in an early stage.
I am currently trying to code a converter for openoffice based on
PyODConverter:
http://www.artofsolving.com/opensource/pyodconverter
My goal is to be able to run my script from anywhere in the system (put
it in Path) and then convert a file from/to openoffice formats to other
formats such as doc/pdf etc.
My main problem is how to issue system commands and then run the above
script.
PyODConverter needs OpenOffice.org to be running as a service which can
be initiated through the following command on the command line (linux
shell):
soffice -headless -accept=socket,port=8100;urp;
once the service is up and running the conversion process is really
straight forward:
python DocumentConverter.py test.odt test.pdf
where DocumentConverter.py is the ready-to-use converter program
downloadable at http://www.artofsolving.com/opensource/pyodconverter
I want to be able to convert the files anywhere without the need to
start the OOo service seperately.
Therefore I tried to add this code on top of the original converter:
###get OOo service started first:
import os
code = os.system('soffice -headless -accept=socket,port=8100;urp;') #
Just execute the command, return a success/fail code
when I execute this script nothing happens and I would have to cancel it.
Is there any way to start the OOo service from a python script?
Thanks in advance for your help!
Timmie
