A Jupyter notebook can combine executable code, Markdown explanations, and saved outputs in one document, according to the JupyterLab notebook guide. That format points to the quickest decision: choose the tool that matches your course’s expected files and working style.
Symptom: You’re unsure whether to start Python in JupyterLab or VS Code.
Fastest fix: Use JupyterLab for lessons built around interactive notebooks; use VS Code for Python files, debugging, and multi-file projects. You can use both when your course moves from exploration to a finished project.
This guide is for students starting Python who haven’t been told which editor to use, learners whose course requires notebook files, and beginners ready to organize code across a project.
Start with the course deliverable
Before choosing an editor, find out what you must submit. A notebook, a single .py script, and a project folder are different deliverables, even if they contain similar Python code.
Check the course page, assignment instructions, and any sample submission. Look for the required file extension, whether explanations or screenshots are expected, and how the instructor will run or review your work. If the instructions show an .ipynb file, plan around a notebook workflow. If they require a Python script or a folder containing several files, plan around regular code files.
A tool opening a file doesn’t prove that the file is ready to submit. You still need to check whether the course can open it, whether its code runs as expected, and whether the saved version contains the work your instructor expects.
Course check: If the assignment gives you a sample file, open and save that file using your intended tool before you build the rest of your work around it.
JupyterLab is designed to work with notebooks, where you can combine code cells with formatted text and outputs. The JupyterLab documentation describes this notebook model. VS Code also supports notebooks through its Jupyter extension; its official notebook documentation explains how notebooks can be opened and worked with in the editor.
The formats aren’t interchangeable just because both tools can show code. Follow the course’s instructions for the file you create and submit.
Compare the tools by the work in front of you
| Decision point | JupyterLab | VS Code |
|---|---|---|
| Lesson style | A natural fit when the course mixes code cells, written explanations, and visible outputs in a notebook. | Can work with notebooks through its Jupyter extension, while also supporting ordinary Python files. |
| Assignment file | Choose it when the expected deliverable is a notebook and the course materials use notebook cells. | Choose it when the course expects .py files or a project organized around code files; it can also handle notebook work with the appropriate extension. |
| Trying a small idea | Run a cell, inspect its output, and continue experimenting in the notebook. | Use a notebook when you need cell-based exploration, or write and run a Python file when the course expects that format. |
| Debugging | Useful for interactive work, but a notebook can make it harder to see the overall structure of a growing project. | Its Python tooling includes debugging support, as described in the VS Code Python documentation. |
| Project organization | Works for notebooks and related files, but check that your course’s file layout remains easy to understand. | A practical choice when you need to organize multiple source files and revisit code as a project. |
| Setup check | Use the official Project Jupyter installation guide to choose an installation route. | Follow the official Python extension and environment guidance for the setup your course requires. |
The table is a decision aid, not a ranking. A tool can support a workflow without being the right choice for your assignment. Use your course’s file format as the deciding factor when you’re unsure.
Match the feedback loop to the lesson
A notebook divides work into cells. You can write a short piece of code, run that cell, inspect what happened, and add a note beside the result. That makes JupyterLab a good fit when you’re learning a concept through small experiments or following a lesson that mixes explanations and code.
For example, if a class asks you to change a variable and observe how the output changes, a notebook lets you keep the experiment and your explanation together. If the lesson asks you to calculate a result, describe what it means, and then try another variation, the cell-based format supports that pattern.
VS Code can also handle notebook work through its Jupyter extension. The VS Code notebook guide covers notebook editing in the editor. So, a course that provides an .ipynb file does not automatically rule out VS Code. Before committing to it, check that the extension is available in your setup and that it opens, runs, and saves the course’s notebook as expected.
Regular Python files support a different kind of practice. You write code in a .py file and run the script as a whole. This fits lessons that teach program structure, functions, or a sequence of steps that should run from beginning to end. VS Code’s Python documentation covers its Python support, including working with and debugging Python code.
Neither workflow is a shortcut to understanding Python. The useful question is what the exercise asks you to do: explore and record observations, or create a reusable script or project.
Should you start Python in JupyterLab or VS Code?
If your course teaches through notebooks or asks you to show explanations beside results, start in JupyterLab unless the instructor specifies a different tool. If the course is built around Python scripts and project files, start in VS Code. If the course hasn’t chosen a format, try its sample exercise in the tool that best matches the work you expect to submit.
You can also use the tools for different stages. Explore an idea in a notebook, then move the code into a Python file when you need a script you can rerun as a project. Only do this when your course allows it; keep the required submission format as the final authority.
Verify the submission, not just the screen
When you choose a tool, test the full hand-in process rather than stopping when the file opens. Use this short acceptance run before you complete a substantial assignment:
- Milestone: Identify the deliverable. Write down the required extension and any instructions about explanations, outputs, or folder structure.
- Milestone: Open the course example. Use the file provided by the course if one is available. Don’t substitute your own format during the test.
- Milestone: Run the provided exercise. Confirm you can execute it using the workflow the course teaches. If it relies on an extension or a particular environment, check that requirement before starting the assignment.
- Milestone: Save the work. Save the file where you can find it again, using the location and naming pattern the course expects.
- Milestone: Close and reopen. Open the saved file again and confirm your code, explanations, and expected results are still there.
- Milestone: Check the hand-in copy. Confirm you’re submitting the saved file or project folder—not an unsaved tab or a different copy.
This check catches a common beginner mistake: treating visible output as proof that the right work has been saved. In a notebook, code, explanatory text, and outputs may all appear together, so inspect the saved document before submitting it. In a script-based project, check that the file you run is the one you plan to hand in.
If the course provides no sample, make a tiny test file in the required format. Save it, reopen it, and follow the course’s instructions for running or submitting it. Ask the instructor before changing formats if the instructions are unclear.
Move toward a project workflow when the work grows
A notebook is still useful when you begin learning larger topics. The decision changes when your assignment asks you to manage reusable code, debug a program, or work with several related files.
VS Code’s official Python documentation describes Python debugging support. That can help when you need to pause code and inspect what it is doing, rather than only looking at the final result. When you’re choosing based on debugging, verify that the course’s Python setup and the files you’re using work with that workflow; don’t assume a feature is ready simply because the editor is installed.
Project organization is another useful signal. If your code is spread across functions, helper files, and resources, a regular project structure can make it easier to locate and maintain each part. In VS Code, keep related files together and check that you can identify the file the course expects you to run. If your class is still asking you to submit one notebook, don’t move the assignment into a project folder without permission.
A notebook can also become difficult to follow if you rely on cell outputs from earlier experiments without checking the saved work. If results seem out of step with the code you see, rerun the relevant cells in the order your lesson specifies and inspect the final saved notebook. Keep this as a verification habit, not a reason to abandon notebooks altogether.
When your course changes direction: Keep using the required notebook for notebook assignments. Add VS Code when you start building regular Python scripts or organizing a project, rather than converting a required submission without checking with your instructor.
Check the Python course environment before assuming you need a Mac
Python tool choice and computer choice are separate decisions. You can learn ordinary Python concepts without treating macOS as a requirement. First check the course’s operating-system instructions, required software, and any libraries or tools the assignments name.
An instructor may require a particular setup for a course task, but the requirement should come from the current course instructions—not from a general assumption that Python requires a Mac. Check whether you need a macOS-specific application or a task that must be verified on macOS. If the course only asks for standard Python scripts or notebooks, follow its stated environment requirements instead of buying or renting hardware pre-emptively.
Xcode is a separate case from general Python practice. If a course task specifically requires Xcode, review Apple’s Xcode system requirements and compare them with the course instructions before deciding what device or environment you need. Don’t assume that installing a Python editor will meet an Xcode requirement.
If you are considering a remote Mac for a course that genuinely needs macOS, compare the course’s file workflow and software requirements with the available environment before you rely on it. The macminirent guide collection can help you review Mac-related setup questions. For student assignments, also think about where your files are stored and what you’re permitted to upload; review the data protection information before handling coursework or personal data in a remote environment.
Finish with a course-file decision
For a course built around interactive lessons, notebook files, or data exploration, choose JupyterLab unless your instructor names a different workflow. For a course that asks you to submit Python scripts, debug code, or manage a multi-file project, choose VS Code. If you’re unsure, test the course’s example file and submit a reopened copy in the required format before settling on a tool.
You don’t need to turn this into a permanent either-or decision. Use a notebook for exploration when the assignment calls for it; use a code editor when you need to build and maintain regular Python files. Keep the course deliverable at the center of both choices.
For ordinary Python practice, your current computer may already be enough. A remote Mac is worth considering only when a course actually requires macOS-specific software or you need to verify work in a Mac environment. Compared with a local computer, a remote setup depends on your network connection, requires you to manage access to remote files, and may not suit tasks that need direct access to local hardware. If those constraints are acceptable and you need a temporary Mac environment for a defined course task, review the macminirent remote Mac options and check the course requirements before choosing a rental.
