Run Python online in your browser

A free online Python playground and compiler. Write Python 3 in your browser, hit Run, and the output comes back in seconds. No install, no sign-up, no local Python setup to worry about.

The editor is built on the same engine as VS Code, so you get syntax highlighting, autocompletion, and error squiggles. Your code runs server-side in a sandboxed Python 3 environment - whether you're checking a list comprehension, testing a regex, or walking through a tutorial exercise, this online Python compiler gets you from idea to output in seconds.

What makes this Python playground useful

Instant Python execution - write code, press Run, and see output from the online Python compiler in seconds.
Full Python 3 syntax highlighting, autocompletion, and clear error messages, powered by the same editor engine as VS Code.
Stdin input is wired into input(). Type one line per line in the input box and the playground feeds them in order, the same way python script.py would read from the prompt.
NumPy, pandas, requests and pytest come pre-installed, so you can run real data-analysis snippets, HTTP calls and tests - not just toy examples. Python 3.11 with the full standard library, no virtual environment to configure.

What you can build in the Python playground

List comprehensions, dictionaries, and f-strings - the core Python idioms, tested line by line.
Small data-processing scripts that read a list, transform it, and print the results.
Interactive scripts that read from input(). Feed lines into the stdin box and practice interview-style problems the same way you'd run them locally.

Python online playground FAQ

Is the online Python playground free?

Yes, the Python playground is free to use. There's no sign-up, no install, and no Python 3 interpreter to configure - just open the page and run code.

Do I need to install Python to use the online compiler?

No install needed. You don't need Python on your machine, an IDE, or a virtual environment. The online Python compiler runs your code server-side and returns the output in seconds.

Does the Python playground work on mobile and Chromebooks?

Yes. The Python playground runs in any modern browser, on desktop, tablet or mobile. It's a good option for running Python online from a Chromebook, iPad, or school computer where you can't install Python.

Does the Python playground support input() and stdin?

Yes. The playground has a stdin input box: type one line per line and the Python input() function reads them in order, the same way running python script.py locally and typing at the prompt would. Useful for interactive scripts, interview problems, and any code that expects stdin.

How do I learn Python after trying the playground?

Edit the sample code, press Run, and iterate. When you want something more structured, Coddy's interactive Python course walks from variables to classes with hands-on exercises after every concept.
