Programming :: Python Error - List Index Out Of Range (Web Scrapper)
Feb 18, 2011
Having a bit of an issue with Python while trying to write a script to download every rar file on a webpage. The script successfully downloads any link that doesn't contain any spaces, etc. But when it hits a url like: [URL] (Classical Spelling).rar. It fails...I'm sure this is something simple, but I'm so new to python I'm not sure what to do!
Code:
import urllib2
import os
os.system("curl [URL] -i rar|cut -d '"' -f 2 > temp.out ")
infile =open('temp.out', 'r')
for url in infile:
print url
#url = "[URL]"
So I have been trying for 8 hours to try to get the index of an element from a list in a Makefile. The problem is that after I get the index using all the methods I have tried, the index cant be used in the "word" function:
for instance: $(OUTPUT2) : INDEX = $(shell echo $(OUTPUT2) | sed -r -e "s/[ ]+/ /g" | grep -n $@ | sed 's/^([0-9]*):.*/1/')
will create a variable INDEX defined specifically for each member of OUTPUT2, so that each output knows its index. Unfortunately, when I pass this $(INDEX) into word, it doesn't work:
$(OUTPUT2) : $(word $(INDEX), $(INPUT1)) $(word $(INDEX), $(INPUT2)) echo $(INAME) $(TMPBASE) $@ and I get the error: Makefile:16: *** non-numeric first argument to `word' function: 'num'. Stop.
I feel like if I could just convert a string to a Makefile acceptable number this would just work....
I am trying to get a list of running processes using audio (using gstreamer), just like in gnome-volume-control, under applications, but have so far been unsuccessful in finding anything in either the gtk or gstreamer library, anyone out there who can point me in the right direction?
I have up until now been able to use the add-apt-repository command without issue but right now it keeps returning an IndexError.
The error is below:
Code:
Select allx@y:~$ sudo add-apt-repository ppa:/kilian/f.lux Traceback (most recent call last): File "/usr/bin/add-apt-repository", line 122, in <module> shortcut = shortcut_handler(line)
[Code] ....
IndexError: string index out of range
I have tried using the command with an empty ppa (just sudo add-apt-repository ppa:) but that comes with the same error. Googling the issue only brought up some bugreports of a month back, and I've used the command with success a few days ago.
create a tar file from a list? My script returns the error: AttributeError: 'list' object has no attribute 'startswith' I want to create a compressed tar file containing the directory /usr/lib and the files in the list assigned to variable b.
code:
import tarfile tar = tarfile.open("backup.gz", "w:gz")
I want to build a bash script, which can ping a range IP adresses which will be filled in by the admin. If there is no IP-adress filled in, then the script must ping the subnet where the system is logged on. So if my ip is 192.168.1.6, then the script must ping from 192.168.1.1 till 192.168.1.255 Or else, if there is given a beginning and ending ip it must ping that!
The first part of the bash script is to ping a given range (see below). But there is one problem, how can I tell the script to ping from $begin till $end, [..] is of course wrong! But what must be filled in there???
echo "Enter beginning IP-adres:" read begin echo "Enter ending IP-adres:" read end ping -c 1 $begin [..] $end
The second part is to find my own ip and ping the whole range.. How to do that? I only can find my own IP, but I cant ping the whole range,, how to do that?
I'm having a bit of trouble with a regular expression I'm trying to write and I'm not sure if it's something Tcl specific or my lack of regexp understanding.
[Code]...
I get a number of strings passed to a proc in the format 3|x where x is a number, either 0 or within the range 5-12. My understanding is that that regexp will match the literal '3' followed by a '|', the escapes the special meaning of |, and then 0 or, because of |, a number within the range 5-12. However I'm getting the error 'couldn't compile regular expression pattern: invalid character range'.
I am building a python script which works same as SMTP protocol. I have build separate functions in that for each command of SMTP, and after this i have integrated all those functions in a new function named as send_mail(so that i don't have to execute every function separately for every command). Now, when i execute the script for the first time it runs successfully, but for the second time it gives the error of "BROKEN PIPE". I really can't make out how the socket is getting closed.
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.
I need to write program (preffer Python) to change range for users. Does anyone know some library which can help me to do that? Maybe someone has written program like that?
I have a function definition in a Python 2.x script which take a tuple as one of its arguments, but 2to3 has no answers nor any of my searching on how to represent the same in Python 3.x
How would I list 4 users ID numbered 10, 11, 12 and 13 from my users list and output them to a file busers where their names are numbered by ascending order? How would I accomplish that on a one line command?
I am trying to get this script to work. The purpose is to download a list of modules from the slax.org the list consist of a list of module numbers. What I am trying to do is Download the file or the file name corresponding to the number in the list.the list is comma delimited. this is what I have done so far and I am a stand still.
#!/bin/sh # Wget script to retrieve modules from slax.org modules # # ----Begin of user defined values ----- # Path to wget
I am trying to port c & c++ open source code onto embedded target(MIPS).It compiles fine on x86/RH4. When I try embedded platform specific tool chain as follows, I get following error:
I tried different combinations. It did not help. My idea is to port an open source code that works fine on X86/Linux to an embedded target based on MIPS.
I am having a little trouble with a Bash shell script that I am working on. It is intended to read the information out of a gedcom genealogy file and determine who has lived in a particular area and output a report based upon who lived in a given area (like the different sections of a bygdebok for example). I am having a number of issues.
1) I can't seem to figure out how to get a variable to work as the index of an array. For example, I am trying to use the variable $individual to count which individual is being read in from the .ged file, and once that is figured out, next I will read in the individual's name, so I would like to create an array of names using the variable
Code: $individual as the index of the array. However, if I try the code Code: name[$individual]=$lineoftext;
[Code]....
I included only the last few lines of output as to not take up too much space because the output goes on forever, but you get the point from the example. This output has nothing to do with what the final output of the program is intended to be like. It is merely a test to prove that the 2 variables in question are getting their date loaded in properly.
I need a script that can do this: A script that searches all directories and subdirectories for .html files When a .html file is found it creates a index.html file in that folder. It then edits the index.html file and inserts links to all of the .html files that are in that folder into the body. If no .html files are found, it searches for folders. It then creates a index.html file with links to all of the folders.
I want that I click with the mouse on the video, it paused.I notice that there is "BaconVideoWidget" which I guess is the video rendering widget but it don't have signal named "clicked":
i use fedora 12 i can't use yum any more , when i try i find error message it was working correctly and i donn't remember what i did

I get the following message when I try to add or remove programs. This includes when I try to use the Update Manager: Software index is broken. It is impossible to install or remove any software. Please use the package manager "Synaptic" or run "sudo apt-get install -f" in a terminal to fix this issue at first. When I follow this advice, I get the following message:
tom@Compaq:~$ sudo apt-get install -f E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?
If anyone can offer suggestions about this problem, Although I've been using Ubuntu for a while, I'm not very confident with the command line (unless I am copy and pasting commands!)
