To a first-order approximation, Perl and Python run at the same speed. They are both interpreted languages with roughly the same kind of control flow and data structures. The two have wildly different kinds of syntax, but the underlying machinery is fairly similar. Don't make a decision on which to use based on execution speed. If you feel compelled to ignore this advice, then don't make the decision until you've coded your application in both languages and done careful benchmarking with realistic data for your application domain. > I have noticed that Regular Expressions are executed very fast in > Python. Does anybody know whether Python executes RE faster than Perl > does? Same answer as above -- for a first cut, assume they are the same speed. If you insist on a better answer, do measurements on real data. The big advantage the Python has over Perl is speed of development and ease of maintenance (i.e. a year from now, you can still understand what your own code does).
