The Real Python Podcast – Episode #301: Running Python Locally in a Sandbox
TL;DR
Running untrusted Python code locally can lead to security risks, code breakage, or data leaks. Simon Willison developed a sandboxing solution using WebAssembly (WASM) and MicroPython, available as an alpha package on PyPI.
✦ Why It Matters
Engineers can use WASM and MicroPython to safely test untrusted Python code without risking their local systems.
Key Takeaways
- Explore using WASM and MicroPython for sandboxing Python applications.
- Stay updated on Python community releases and tutorials.
- Utilize the subprocess module for managing external processes.
- Consider enrolling in AI coding courses to enhance your skills.
How It Works
The sandboxing solution leverages WebAssembly (WASM) to create a secure environment for executing Python code. MicroPython, a lightweight implementation of Python, runs within this environment, allowing developers to test untrusted code without risking their local systems.
This setup isolates the execution context, preventing malicious code from affecting the host machine.
