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?

View 3 Replies View RelatedI have a list of list and I'd like to sort the list according to the last value of each row.
Let's say we have the list
L1 = [ [1,2] , [4,6] , [78,-3] ]
I wish to get
L2 = [ [78,-3] , [1,2] , [4,6] ]
Is there a simple way to do that in python?
so far I have this
list = open('list.txt')

None of the above works and I've tried everything I can think of.
I have p1,p2,p3,p4 some processes created by me in C. p1, p2, p3 are started individually from several consoles. And I want process p4 to terminates processes p1, p2, p3 if they are running. Which is the easiest way to accomplish that? put all processes in the same process group and send from p4 a kill signal to the group. But I couldn't do that because I cannot call successfully setpgid(getpid(), 15000) from p1-p4. It's there some way to put them in the same group? the processes don't have a child-parent relationship, they are launched manually from consoles.
View 1 Replies View RelatedI'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.
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]"
#url = target
file_name = url.split('/')[-1]
u = urllib2.urlopen(url)
f = open(file_name, 'w')
meta = u.info()
file_size = int(meta.getheaders("Content-Length")[0])
print "Downloading: %s Bytes: %s" % (file_name, file_size)
file_size_dl = 0
block_sz = 8192
while True:
buffer = u.read(block_sz)
if not buffer:
break
file_size_dl += block_sz
f.write(buffer)
status = r"%10d [%3.2f%%]" % (file_size_dl, file_size_dl * 100. / file_size)
status = status + chr(8)*(len(status)+1)
print status,
f.close()

How can I get this on a python program so I can manipulate it as an array?
What I need is, given a process id, list all his children without any clutter (table header, other columns than the pid) What I have is :
ps h --ppid $PID Which gives me:
26277 pts/13 S+ 0:10 cmd1
26280 pts/13 S+ 0:10 cmd2
Using h allow me to hide the table header. Is there a way to tell ps to not print the pts/13 S+ 0:10 cmd part in order to get a list of children process ids separated by carriage return?
how can I check which process is using certain port? Like in a table with processes and used ports...

I would like to do the following: Create a banner for any user logging in through ssh which warns him/her about the number of processors being used already by other users (or conversely the number of free processors). For example, if a user logged in he would then see a message like: Warning! 7 out of 8 processors are in use.I already figured out how to do a banner and with ps -e -o pcpu I can get all processes' %CPU usage. I think I would like to count the number of processes which have more than 90% CPU usage and output this number ("7" in the example) in the banner
