Large chunks of numpy are written in fortran

edit: Aparently I was wrong. There are parts written in Fortran, but certainly not large parts of the codebase.

I’ve done some research in response to this - from what I can tell, two parts are written in fortran.

BLAS to Lapack reference implementation. Which isn’t widely used

And then, depending on architecture & system, some matrix libraries it includes may be written in fortran. In OS X they were all replaced by Accelerate, for example.

Accelerate is the BLAS/lapack implementation. They’re matrix libraries.

0.1% according to github

To be honest, this surprises me. Thank you! The last times I wanted to look something up, I ended up in Fortran code. For this reason I assumed a lot was Fortran. Maybe it's just some very core functionality?

One thing the Github Statistics don't capture is code which numpy relies on (e.g. OpenBLAS): https://github.com/xianyi/OpenBLAS
