A focused Python workspace

Less setup,
more practice.

Python Starter brings editing, execution, input, output, and lessons into one clear workspace so you can focus on code and results.

01 / WRITE

Organize real Python projects

Edit multiple source files with automatic saving. Add a Flask server and switch between independent client and server workspaces.

defforprint()
02 / RUN

Execute on the device

iPhone, iPad, and Mac use bundled CPython 3.14. Code executes locally; network requests follow your program.

$ python main.py
✓ process finished
03 / LEARN

See output and errors

Prepare standard input, read output and tracebacks, and stop programs that run too long or print too much.

LEARN AND BUILD

From Python basics
to useful projects.

Start with 20 free Python Basics lessons. Learning Pro adds six courses in data processing, files, object-oriented programming, SQLite, NumPy, and HTTP/server development. All courses support English, Chinese, and Japanese.

Learn with feedback

Learning points, explanations, runnable examples, local exercise checks, and reference implementations.

Keep references close

Independent API quick references for Python, NumPy, Requests, and Flask, with examples and content updates.

Choose your workspace

Use the private default folder, select a workspace on Mac, or enable access through Files on iPhone/iPad. Keep backups: deleting the iOS app also deletes its Files folder.

IDE Pro is a one-time purchase for multiple projects and project management. Learning Pro is a separate 1-, 3-, or 12-month non-renewing purchase for paid courses; it does not renew automatically. See features and access details →

Three small steps

Write, run,
understand.

No account, complex project, or environment installation needed.

  1. 1

    Create a practice project

    Start with Hello World, add Python modules, or create a project with a local Flask server.

  2. 2

    Run your program

    Tap Run and Python Starter interprets the code on the current device.

  3. 3

    Read the feedback

    Review output and exceptions, then change the code and try again.

Made for practice
