Python Runtime

The PythonRuntime allows you to run short-lived code on a Python virtual machine.

# my_typegraph.py

from typegraph import typegraph, Policy, t, Graph
from typegraph.runtimes.deno import PythonRuntime

@typegraph()
def example_python(g: Graph):
    public = Policy.public()
    python = PythonRuntime()

    g.expose(
        public,
        add=t.func(
            t.struct({"a": t.integer(), "b": t.integer()}),
            t.integer(),
            # we can provide the code inline using lambdas
            python.from_lambda(lambda x: x["a"] + x["b"]),
        ),
        sayHello=python.import_(
            t.struct({"name": t.string()}),
            t.string(),
            # point to pythoin a file on disc
            module="hello.py",
            name="say_hello"
        ),
