Week1 A.2 Sequence Model>> What does it mean: _, n_a = 20, 100

Yes please:

_, n_a = 20, 100

Im just curious…what is:
_ = 20

I don’t see it used anywhere so what does it mean? Is not enough to write down n_a = 100?
Thank you

Which assignment in Week 1? Which function?

Found it, it’s Week 1 Assignment 2 (Dino Island), in the sample_test() function.

Beats me, that’s some weird syntax. I’ll ask the course authors.
