NumPy

A code output form: Python/NumPy source, via compute-engine's own Python target. The registry format is named Python (aliases python, numpy, py, extension .py, in packages/formats/src/formats.ts); PythonForm is what the In/Out menu calls it, the display-form label in notatio-out.ts. It translates numeric and function expressions into the np namespace; symbolic-only heads — and some combinatorial ones like Binomial — have no NumPy form and emit nothing.

A few emissions are worth knowing (shown below): Exp becomes np.e ** x rather than np.exp, Sqrt/Ln use the complex-capable np.emath.*, special functions pull in SciPy, and exact rationals collapse to floats.
