Sorry if I'm mistaken, but I thought that the Java VM was a complete
virtual processor, whereas Python (just as Perl) merely generates a parse
tree on compiling the code.
If the Python VM is however a full Virtual Machine, then I apologise,
because it appears my knowledge is out of date.

Actually, strange as it may sound, I like both Perl and Python. But Perl
really shines in text processing. Just running through a file and
extracting the bits you need with regular expressions is so easily done.
Constructs like the 'while (<FILEHANDLE>)' loop, which takes a line from a
file until EOF (meanwhile assigning it to the default variable) make it
really easy to toss of simple filter scripts.
For sure Python can do that too, but it takes a little more setup work,
and the clean (more or less <grin>) integration of regexps in looping
constructs such as above, makes me prefer Perl to do data extraction.
