And is NumPy "Numb Pie" or does it rhyme with "lumpy"? (My apologies to everyone who will picture something lumpy next time they're doing a bunch of math).

I've always heard "Numb Pie"

It think it's pronounced numpy...

That said, I've always rhymed it with lumpy, haha

In conference talks, most people (including NumPy's creators) pronounce it "numb pie".

I pronounce it like the planet, and everyone else I've met in Jupyter leadership (including Fernando and Brian) also pronounce it like the planet.

I just pronounce it the same as the planet Jupiter.

Oh, I say the Py part as in Python... Is it wrong?

Yes. The creators pronounce it exactly like "Jupiter", where the unstressed middle "i" vowel becomes a schwa.

Fernando Perez says "Jupiter". It's his baby, "Jupiter" it is.

Like the planet
