Python Starter

Learn Python by writing real code. Run locally with 20 free lessons, interactive input, instant feedback, and private on-device processing.

Python Starter is a focused coding and learning environment for beginners who want to learn Python by writing and running real code.

Write Python programs, provide standard input, and view program output and exception tracebacks - all within the app. Python Starter includes CPython 3.14 and its standard library for local execution on iPhone and iPad. Your source code, input, run results, and program output are processed locally and are not uploaded to developer servers.

Learn by Writing Code

The included Python Basics course provides 20 free lessons in four sections covering:

• Your first Python program, variables, numbers, and arithmetic
• Decisions, comparisons, loops, and small programming projects
• Functions, strings, lists, and dictionaries
• List transformations, the standard library, sorting, searching, exceptions, and a final Grade Analyzer project

Each lesson includes an explanation, example code, an editable exercise, expected output, and automatic local validation.

A Practical Python Workspace

• Write and edit a main.py source file
• Run Python code locally on your device
• Prepare standard input before running a program
• Send input while a program is waiting and send EOF when finished
• View program output, errors, and exception tracebacks
• Stop programs or handle execution timeouts and excessive output
• Save your work automatically
• Duplicate, rename, delete, and restore projects with IDE Pro

Private by Design

• No account or login is required
• Your code stays on your device
• Source code, input, run results, and output are not uploaded
• There is no cloud sync, remote execution, or cloud backup

Python Starter includes one editable local workspace for free. Python Starter IDE Pro is an optional one-time purchase that unlocks multiple local projects and complete project management features.

The iPhone and iPad runtime supports Python's standard library and the native extensions included with the app. Python Starter does not provide pip installation or guarantee compatibility with arbitrary third-party native wheels and packages.

Whether you are writing your first script or practicing essential Python concepts, Python Starter provides a simple place to learn through code.
