I love Perl. I have started using Python more, partially because it's
in vogue, but largely because hastily written code seems to come out
"cleaner." One certainly can write clear, maintainable code in Perl,
but doing so in Python feels a bit more natural. For example:
- Object orientation was a design goal of Python, but had to
be retrofitted onto Perl.
- Every module I write in Perl contains:
use warnings; # Should have been the default.
use strict; # Check for dubious constructs.
# Probably some export code like this:
our @ISA = qw( Exporter );
our @EXPORT_OK = (
# ...
);
# "Real" code.
# ...
1 # Return good value on import.
In Python, none of this is necessary.
- Python knows what indentation means, so I get to skip a
lot of curly braces.
For one-liners, I still use Perl, specifically because:
- I don't have to import "os" and "sys" modules just
to basic tasks like issuing system commands.
- Perl will auto-vivify variables with reasonable
default values. E.g., if I ++$count, Perl has
enough intuition to know that I wanted $count
initialized to zero.
- Perl lets me use very clean syntax for subroutine
invocation, e.g. by skipping parentheses and being
aware of (list or scalar) context.
Hope this helps.
