FreestylePython
Add Python runtime to your VMs.
The Python integration adds Python 3 to your VM and provides helper methods for running Python code.
Installation
npm install @freestyle-sh/with-python freestyle-sandboxesUsage
import { freestyle } from "freestyle-sandboxes";
import { VmPython } from "@freestyle-sh/with-python";
const { vm } = await freestyle.vms.create({
with: {
python: new VmPython(),
},
});
const res = await vm.python.runCode({
code: 'import json; print(json.dumps({"hello": "world"}))'
});
console.log(res);
// { result: { hello: 'world' }, stdout: '{"hello": "world"}\n', statusCode: 0 }API
vm.python.runCode({ code })
Executes Python code in the runtime.
const res = await vm.python.runCode({
code: `
import json
data = {"sum": 1 + 2, "list": [1, 2, 3]}
print(json.dumps(data))
`
});
console.log(res.result); // { sum: 3, list: [1, 2, 3] }Returns: Promise<RunCodeResponse>
type RunCodeResponse<Result> = {
result: Result; // Parsed JSON from stdout (if valid JSON)
stdout?: string; // Raw stdout output
stderr?: string; // Raw stderr output
statusCode?: number; // Exit code
};Example: Data Processing
import { freestyle } from "freestyle-sandboxes";
import { VmPython } from "@freestyle-sh/with-python";
const { vm } = await freestyle.vms.create({
with: {
python: new VmPython(),
},
});
const res = await vm.python.runCode({
code: `
import json
# Process some data
numbers = [1, 2, 3, 4, 5]
result = {
"sum": sum(numbers),
"average": sum(numbers) / len(numbers),
"squared": [n ** 2 for n in numbers]
}
print(json.dumps(result))
`
});
console.log(res.result);
// { sum: 15, average: 3, squared: [1, 4, 9, 16, 25] }
