About this editor

Write Python, press Run, read stdout below. Scripts, homework checks, interview prep — no pip on your machine.

Practice algorithms, debug homework, or try stdlib modules in a real Python 3 sandbox—not a toy subset. Matplotlib and stdin work where the image allows, so contest-style I/O and quick plots are possible. Save a snippet to turn your session into a shareable Python playground link.

Key features

Python 3 runs server-side

Python 3.x in a sandbox with the standard library — the usual setup for scripts and interview questions.

One-click Run

Output, stderr, and compiler errors land in the panel below. No local install.

VS Code–like editor

Syntax highlighting, bracket matching, and shortcuts that feel familiar if you use VS Code.

Shareable links

Save with a title and copy the URL — handy for reviews, homework, or interview screens.

No setup

Open the page and start typing. Account optional for basic runs.

Room to grow

Need multiple files? Open a cloud workspace from the top bar.

Matplotlib & stdin

Plot when matplotlib is in the image. Read stdin for contest-style solutions.

Getting started

  1. 1
    Write your code

    Type or paste Python in the editor. A starter template is there if you want to run something immediately.

  2. 2
    Press Run

    Check the output panel underneath for results or errors.

  3. 3
    Edit and rerun

    Change a line, run again. Most people loop here until the output looks right.

  4. 4
    Save for a permalink

    Add a title when you save. You get a link you can send to a teammate or drop in a doc.

  5. 5
    Bigger project?

    Cloud workspaces handle multi-file repos and longer sessions. Link is in the top nav.

Common questions

Is this Python compiler free?

Yes. No payment and no account required for a quick run. Sign in if you want saves tied to your profile.

Do I need to install anything?

No. Code runs on Codeground servers in a sandbox. Just open the page.

What Python version runs here?

Python 3.x in a sandbox. Stdlib is there; extra pip packages only if pre-installed.

Can I share my code?

Save with a title to get a permalink, or share the playground URL as-is.

Works for interviews?

Yes. Share a ground link, or use interview mode for a live shared editor.

Multiple files?

This page is for single-file snippets. Use a cloud workspace for full projects.

Will my code still be here tomorrow?

Anonymous sessions can reset. Save with a title (and sign in) for a stable link.

Why use this instead of installing locally?

Good for quick tests, learning, and sharing a snippet. For large offline work, a local IDE still wins.

Is this an online Python IDE or playground?

A browser playground with syntax highlighting and one-click Run — run Python online without a full local install. Cloud workspaces cover multi-file projects.

Can I pip install packages here?

This page is for single-file snippets with what is already in the image. Custom deps need a cloud workspace.

Is there a free Python playground?

Yes. Run Python 3 online for free—open the editor, press Run, no signup required for basic use.

Is this a Python online IDE?

Browser-based IDE with highlighting and Run. Single-file focus; multi-file Python projects belong in a cloud workspace.

Can I run Python online without installing Python?

Yes. The interpreter runs on our servers. You only need a browser—no python.org install on your laptop.
