What does @z mean in Python

Question

I'm reading someone else's code and I don't understand what is the use of @z here:

x = np.linalg.inv(P)@z

and when i Google @z (here), it seems that the search engine ignores the @, how come?

Perhaps you weren't aware of the name of the @ symbol ('at'), although that seems unlikely in an age where even the homeless have e-mail addresses, but in general it's a good idea to try searching for the name of a symbol if a search including the symbol doesn't turn up anything. — Grismar, Feb 19 '22 at 22:42

From the numpy docs:

The @ operator can be used as a shorthand for np.matmul on ndarrays.
x1 = np.array([2j, 3j])
x2 = np.array([2j, 3j])
x1 @ x2
(-13+0j)
