Your have Fortran:

You rescue every princess in the world, in a massively parallel operation. Wait, none of these was a captured princess. You've accidentally kidnapped a lot of people. But you did it really fast.

You have Python:

You setup a virtual castle and create an elegant three line rescue solution. To get your elegant three line solution working at the actual castle, you level the castle one brick at a time. You accidentally free princess manually, and she helps you debug the final version of the now useless rescue script. But she agrees that it is a really elegant script.
