As most readers know I am not a fan of programmers who believe that a single language will meet all their programming needs. Once you get past the novice stage you should, in my opinion, have a reasonable selection of languages that you can use with some fluency. On the other hand, only language lawyers and collectors have the time to study every language that crosses their horizons.
Several languages support script type, cross platform programming supported by an interpreter.
If you are fluent in a language such as Perl then Python may not add enough utility to justify study. Python has a great deal to offer. Indeed if I were still teaching adolescents about computing I would seriously consider using Python as an introductory language. If you have made the decision to try Python your next problem will be to find a book that will answer your needs. This latest addition is very welcome.
