The simplest way is to select the block of code in your editor and use the 
'comment-region' command. If this doesn't work, upgrade your editor.

Most editors have a command to do this although obviously the name will 
vary slightly: Idle calls it 'Comment Out Region', SciTe calls it 'Block 
Comment', emacs calls it 'comment-region'.
