Where do you draw the line? Most of CPython is written in C including the arrays package (https://docs.python.org/3/library/array.html) mentioned in that article.

Yes, pure Python is slower and takes up more memory. But that doesn't mean it can't be productive and performant using these types of strategies to speed up where necessary.

With respect, I think you're clouding things by trying to defend what is really defensible. Okay then.

> Where do you draw the line?

Drawing the line at native python, not pulling in packages that are written in another language. Packages written in python only are acceptable in this argument.

> But that doesn't mean it can't be productive and performant using these types of strategies to speed up where necessary.

No one said it couldn't. What we're saying is that it pure python is 'slow' and you need to escape from pure python to get the speedups.

I agree that pure Python isn't as fast as other options. Just comes down to a productivity tradeoff for developers. And it doesn't have to be one or the other.

Agreed, then!
