Herramientas

Los programadores que usamos Python, no dependemos de herramientas externas al lenguaje en la forma que se depende de ellas cuando se usa un lenguaje como Java.

I can't tell you how many times I've heard people say they wouldn't use Ruby because it lacks automated refactoring tools. Ruby doesn't actually need them in the way Java does; it's like refusing to switch to an electric car because there's no place to put the gasoline. But programmers are a stubborn bunch, and to win them over you have to give them what they think they want.
