Little script that I use to change the Pulseaudio volume with my keyboard bindings

pulseaudio-volume-control.py

#!/usr/bin/env python
import commands, sys, os
padump = commands.getoutput('pacmd dump').split('\n')
if sys.argv[1]=='toggle':
    for muteline in padump:
        if 'set-sink-mute' in muteline:
            cmd, src, val = muteline.split()
            val = {'yes':'no', 'no':'yes'}[val]
            os.system('pacmd {cmd} {src} {val} >/dev/null'.format(**locals()))
else:
    for volline in padump:
        if 'set-sink-volume' in volline:
            cmd, src, vol = volline.split()
            vol = int(vol,16)
            if sys.argv[1][0] in "-+":
                vol += int(sys.argv[1])
            else:
                vol = int(sys.argv[1])
            if vol<0: vol=0
            if vol>65535: vol=65535
            os.system('pacmd {cmd} {src} {vol} >/dev/null'.format(**locals()))
