[Level 1] MP3 editor in Ubuntu.

If you want to modify mp3 in Ubuntu,
you could use "audacity".
And you could download it from reposity.
The commands as the following.
# apt-cache search audacity
create-resources - shared resources for use by creative applications
audacity - fast, cross-platform audio editor
audacity-data - fast, cross-platform audio editor (data)
audacity-dbg - fast, cross-platform audio editor (debug)
vamp-plugin-sdk - audio analysis and feature extraction plugins (SDK)
# apt-get -y install audacity

After for a while, I heard a good tool to convert mp4 to mp3 call avidemux
# apt-cache search avidemux
libavidemux0 - a free video editor - shared libraries
avidemux - a free video editor - GTK version
avidemux-cli - a free video editor - command line version
avidemux-common - a free video editor - Internationalization files
avidemux-plugins-cli - a free video editor - CLI plugins
avidemux-plugins-common - a free video editor - common files for plugins
avidemux-plugins-gtk - a free video editor - GTK plugins
avidemux-plugins-qt - a free video editor - Qt plugins
avidemux-qt - a free video editor - QT version
# apt-get -y install avidemux

Wish this helps. regards, Stanley Huang

Image
If you want to give a list for user to choose, you can use the option "--list". The command synopsis as below: SYNOPSIS      zenity  --list [--title=title] [--window-icon=path] [--width=width]    [--height=height] [--timeout=seconds] [--column=text] [--checklist]       [--radiolist] [--separator=character] [--multiple] [--editable] [--print-column=number] [--hide-column=number] Just like " --calendar ", if you press "ESC" key or click button "Cancel", the return code will be "1".

[Level 2] iif in Python

If you want to implement iif in Python, please refer to the following sample code: #!/bin/env python def iif(b): return 'It\'s True' if b else 'It\'s False' print iif(True) print iif(False) And the following sample, guess what will you get! #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % 'Ture' if b else 'False' Result: $ ./iif.py b: Ture False The second result is "False", not "b: False". Why??? Because the prededence of string concatenation is higher than if. Therefore you need to use () to make it correct. #!/bin/env python b = True print 'b: %s' % 'Ture' if b else 'False' b = False print 'b: %s' % ('Ture' if b else 'False') Wish this helps. regards, Stanley Huang
