Not school-issued ones, as my son and I discovered. He told me that the school had assigned a Chromebook to each student. I said: "Great, let's install Python on it."

Nope. Locked down like a crab's arse.

Sad. The Chromebook went under his bed, and came back out at the end of the school year when it had to be returned.
