Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming.

I've already used line split stuff to transform my data into something like this in a text file:
Code:
['1', '1', '3', '20.7505207']
['2', '1', '3', '23.0488319']
['3', '1', '3', '-1.5768747']
['4', '1', '3', '-26.4772491']
[code]....
How can I get this on a python program so I can manipulate it as an array?

I want to be able to create an RPM that will install python 2.7.1 along with sqlite 3.7.3, MySQL-Python-1.2.3 on a CentOS 5.5 x86_64 host(s) in a directory (e.g. /opt/python2.7). Once that's done, I want to be able to alias the new python binary in .bash_profile so that my developers can begin using it.
I understand 2.7.1 can't be installed on a CentOS host but I've done the above using a shell script successfully. If you search hard enough, I posted my script on line . However, I need to create the RPM for political reasons. Besides placing the source file(s) in the SOURCES directory, what do I need to do in the spec to be able to successfully create an RPM installer?
Please be gentle with me. I've been drinking the Windows cool-aid for most of my IT career so, this is one of my first attempts of becoming a better DevOps Admin.

I run Wheezy Xfce 64-bit. I went through the Synaptic listings and added Python 3.3.2 and Tkinter for it, and that works fine; but for some reason PyGtk is available only for Python 2.7, not for Python 3.3, unless I'm just using the wrong way to try to find it. Is there a PyGtk available for Python 3.3 in Wheezy, and, if so, how do I install it and then import it once it's installed?

I have a code that uses the Firefox webdriver with Selenium to execute a couple javascript commands and fetch me some info. Since Debian doesn't use Firefox by default, and Selenium doesn't recognize Iceweasel as the equivalent of Firefox (which may be reasonable, but still kinda dumb), I downloaded and extracted the firefox-28.0 bz2 folder to my desktop. Next, I used the top answer suggested here to point Selenium to the binary:
Code: Select allfrom selenium import webdriver
from selenium.webdriver.firefox.firefox_binary import FirefoxBinary
[...]
binary = FirefoxBinary('~/firefox/firefox-bin')
driver = webdriver.Firefox(firefox_binary=binary)
However, it results in this error message:
Code: Select allTraceback (most recent call last):
File "./seltest.py", line 19, in <module>
driver = webdriver.Firefox(firefox_binary=binary)
File "/usr/local/lib/python2.7/dist-packages/selenium/webdriver/firefox/webdriver.py", line 59, in __init__
self.binary, timeout),
[Code] ....
Did I set the binary path incorrectly or something?

I'm trying to search for several strings, which I have in a .txt file line by line, on another file.
So the idea is, take input.txt and search for each line in that file in another file, let's call it rules.txt.
So far, I've been able to do this, to search for individual strings:
Code: Select allimport re
shakes = open("output.csv", "r")
for line in shakes:
if re.match("STRING", line):
print line,
How can I change this to input the strings to be searched from another file?
So far I haven't been able to.

I going through the Python course on Codeacademy. I have some trouble understanding what I'm doing wrong. This is my code below:
Code: Select alldef count(sequence, item):
total = 0
for x in sequence:
return x
if x in sequence:
total += 1
return total
print count([1,2,1,1], 1 )
The code gives me an error: "Oops, try again. Your function fails on count([1],7). It returns 1 when it should return 0."
It should be outputting 3 because 1 occurs 3 times in the list.

I have written a shared library and successfully used debhelper 9 to create a Debian package from source using a Makefile generated by cmake. I then went about writing a python wrapper to that library and wish to package that wrapper in with the library so I can have a single distributable rather than 2 separate ones.
All of my attempts so far have me placing my python source and a setup.py file in the same directory as the makefile at the time where I call debuild.
From here I have tried a couple different configurations to my debian/rules file as seen below:
Attempt 1:
# -*- makefile -*-
%:
dh $@ --with-python2 --buildsystem=python_distutils
This try seemed to package up the python stuff nicely but proceeded to ignore my makefile for the shared library and therefore ultimately failed.
Attempt 2:
# -*- makefile -*-
%:
dh $@ --with-python2
This try ran make, but completely ignored the python stuff. From some research I have gathered that the --buildsystem flag tells debuild to ignore any makefiles in the directory, which obviously causes a problem in my case.
Another attempt was to modify the build dependency to first run make and then call the python build process that file looked like this
Attempt 3:
# -*- makefile -*-
build:
dh $@
dh $@ --with-python2 --buildsystem=python_distutils
%:
dh $@ --with-python2 --buildsystem=python_distutils
This appears to somewhat work as both processes do build, but a few of the python files are still not getting installed.
Is this the way I should be going about doing this? I've noticed that most python wrappers tend to package themselves individually and then make that package dependent on the library it is attempting to wrap.

Just installed Debian 8 last night and trying to run one a few of my scripts that use easygui (a front-end for python-tk basically) and I keep getting alloc: invalid block any time a file or folder selection dialog is presented. I'm able to select a file/folder with no issues, but once the dialog closes I get a variation of what appears to be a memory error followed by alloc: invalid block.
Here's one of my scripts that does it. This one pops up a file selection dialog pretty early on to ask for a file to check, and as soon as I select any file the dialog closes and that error appears in the terminal. It happens whether I run it with Python 2 or Python 3. You will need to install python3-easygui for this script to run properly if you want to check for yourself what happens. This is a first time encountering this error for me.

When I getch() a key event (UP arrow key), the getch() function return a string of characters that I cannot compare with curses.KEY_UP constant. Here is the code I use :
while True:
w = gb.scrn.getch()
c = chr(w)
otp = 'touche:'+str(w)+' '+str(c)+"
[Code]...
It seems like getch() return three distincts bytes while I would retrieve it with a single ord() instruction in python like describes in curses/python documentation.

in ubuntu 10.10, I have installed python 2.7. I would like to use apt-get to install packages to this version of python but I haven't been able to figure out howThings I have tried without success:changing the symlink at /usr/bin/python to point to /usr/bin/python2.7 - even after doing this apt-get still installs stuff to python2.6.Set up python2.7 as the primary alternative using update-alternatives - doesn't work

I work with python and I use emacs as my IDE tool. I have been running Debian Squeeze (6.0.9) for some time now with emacs 23.2.1 and ecb 2.32. I am able to access my python methods in the ecb-methods window with no problems. However I recently upgraded my desktop to Debian Wheezy (7.5) running emacs 23.4.1 and ecb 2.40 but I have lost access to the methods in the ecb-methods window. The window is just empty while the others (directories, sources and history) are all populated. I have a second laptop which I decided to upgrade to Debian Jessie, however Jessie recommends emacs 23.4.1 which is running with ecb 2.40 also. The result is the same as on Wheezy.
I have used the ecb menus and googled for a solution or even just a mention that such a problem exists but have come up with nothing. Either I have a unique situation here or am doing something really dumb.
I would like to upgrade to Wheezy or Jessie but I need access to methods in the ecb methods window. How to keep my upgrade and see the methods in the methods window of the ecb system ....

Is there any reason why PyGTK is still at 2.22?
There are warnings generated when using Matplotlib (though execution can continue).
Will we likely see an upgrade before 13.37?

I couldn't connect my Micromax 300G modem in Debian Linux. From internet (in Windows Vista), I came across the information of USB_ModeSwitch and then I downloaded it. While going to install it, I came across the problem that TCL-interpreter is not available in Debian Linux. Then again I restarted my laptop in Windows Vista and connected my Micromax modem and from internet downloaded TCL8.5.10-src.tar.gz. But while going to install it, I came across the problem that " configure: error: no acceptable C compiler found in $PATH " . Also as presently, I am unable to connect my modem therefore I am unable to issue the code:" apt-get update ".

Code: rpm -qi pyOpenSSL yields information pertaining to the version of Python OpenSSL on my server. Can you explain what Python OpenSSL is in simple terms?

I have an existing line of code from a P2 script that I cannot find a solution to converting to P3:
Code:
for i, x in map(None, list1, list2):
I have found the information about converting the simple case:
map(None,x) becomes list(x)
But my googling was unable to find a solution when more than one iterable exists.

I have a python script I wrote a while ago and now I would like to call that script from inside C. I know how to do one command from C, but how would you execute an entire script from C, and passing arguments? Like:
Code:
int main(void)
{
python( myprogram(1 2 3) );
}
So I can pass arguments to my script.

I have a bash script that I want to import in to Python, mainly just to see if I can or not. However in the script I do use some piping of commands into sed to trim it down to what I need. When I tried doing it with the os.system() call, it didn't work. The exact error is
sed: -e expression #1, char 16: unterminated `s' command
However the command that was run can be run in bash without an error. Is there a better/another way to do this? For reference the command is:
Code:
locate -n 1 wp-config.php | sed 's/wp-config.php/
/g' | sed '/wp-config.php/ d' | sed '/^$/ d'
