Today I spend some hours to complete a python project. Because the project should expandable and manageable the functionality is splitted into classes, packages and so on - python best practices.

But, as long as I program with python I don't understand why this language is so hyped! Several years back I wanted to leave Perl as the scripting language of choice (sometimes I still use Perl). As far as I remember I looked at Python and Ruby and finally I decided to use Ruby. Nowadays, When I reexamine this decision I must say that this decision was absolutely right!

There are several Python characteristics that bother me currently:

  • no really clean object oriented design. Under the hood Python and Ruby are closer together then it seems but Python integrates a lot of extension that make this OO design not visible - why? Ruby on the other hand goes another way: it provides a clean OO interface and do a lot that this OO interface is usable. Why must the OO design artificial hidden from the programmer?
  • classes are expandable: with ruby I can add or remove class methods at runtime or even modify already existing class methods. A really great feature which is really handy in some circumstances - where is this feature in python?

Sure, I am no python hacker but from the programmer experience the ruby interface seems quite more matured and cleaner.
