There is sort-of a tradeoff in the syntax choices between the languages.  Perl 
is easier to write because it is flexible and you can use a syntax that 
resembles something you already know (shell/c/awk) with simple changes.  That 
makes other peoples perl less readable, but not your own.  The other win for 
perl is that any operation that would take more than a page of code that you are 
likely to want to do has almost certainly already been done and is available as 
a module on CPAN (and possibly packaged as an rpm).  Does python have anything 
to match that yet?  How many database types can it access with available 
modules?  Perl's DBI/DBD connector list is pretty large.
