In this Daytona SDK tutorial, we provide a hands-on walkthrough for leveraging Daytona’s secure sandbox environment to execute untrusted or AI-generated Python code safely within Notebook. Beginning with straightforward sandbox creation and basic code execution, the guide demonstrates how to isolate processes, install dependencies, and run simple scripts without jeopardizing the host environment. As the tutorial progresses, it delves into data processing with pandas, file operations including reading and writing JSON files, and the execution of complex AI-generated snippets such as recursive functions and sorting algorithms. Finally, it showcases parallel task execution across multiple sandboxes and proper cleanup procedures, ensuring that every resource is managed and disposed of correctly.

from daytona_sdk import Daytona, DaytonaConfig, CreateSandboxParams
We install and import the Daytona SDK (if not already present), then initialize the core Daytona classes (Daytona, DaytonaConfig, and CreateSandboxParams) for configuring and creating secure Python sandboxes. It also brings in standard utilities like os, time, and json for use within those sandboxes.

This DaytonaTutorial class encapsulates a complete end-to-end guide for using the Daytona SDK: it initializes a secure sandbox client with your API key, demonstrates isolated code execution (from simple prints through pandas data processing and file I/O to AI-generated snippets), orchestrates parallel tasks across multiple sandboxes, and finally ensures clean teardown of all resources. Each method is self-contained, showcasing key Daytona features, sandbox creation, dependency installation, safe execution, and resource cleanup, in a clear, step-by-step workflow that’s ideal for running in Notebook.

print(“💡 Make sure your API key is valid and you have network access”)
The main() function outlines the initial setup steps, guiding users to create a Daytona account and generate their API key, then validates that the key has been provided before instantiating the DaytonaTutorial class and running the full walkthrough. If the API key is missing or invalid, it prints clear instructions and aborts, ensuring a smooth first-time experience.
main()
Finally, the above standard Python entry-point check ensures that main() is only invoked when the script is run directly, initiating the Daytona tutorial workflow in a clear and controlled manner.
In conclusion, by following this tutorial, developers gain a comprehensive understanding of Daytona’s core capabilities: creating isolated Python sandboxes, performing secure data manipulations, managing file I/O, running arbitrary or AI-generated code, and orchestrating parallel workloads, all while maintaining strict separation from the host system. The cleanup routines underscore the importance of resource hygiene in long-running workflows. Armed with these foundational skills, users can confidently integrate Daytona into larger machine-learning pipelines, automated testing frameworks, or any scenario that requires the safe execution of dynamic code.
