What is a Python playground?

A Python playground is an online editor where you can write and run Python without installing anything. It is a sandbox for trying ideas and seeing how Python behaves.

Is the playground free?

Yes. There is no paid tier and no account needed: Python 3.13, NumPy, Pandas, Matplotlib, notebooks and multi-file projects are all free.

Can I install additional Python packages?

Hundreds of packages, including SciPy, scikit-learn, statsmodels and Pydantic, load as soon as you import them. Other pure Python packages can be installed from the Packages panel; packages that need system-level C libraries may not be available.

Will my code be saved?

Yes. Your code saves in your browser as you type and is there when you come back. You can also export it as .py files, Jupyter notebooks (.ipynb), PDF or HTML.

Your Python Sandbox

A playground is for trying things out: run a line, change it, and see what happens. pythoncompiler.io gives you Python 3.13 in a browser tab. Code runs inside the browser's sandbox, so it cannot touch the files on your computer.

Divide by zero to see the error, write a list comprehension, or paste import this and press Ctrl+Enter.

Things to Try

Copy any of these into the editor and press Run.

Your First Program

“Hello, World!” and a small star pyramid.

print("Hello, World!")
for i in range(5):
    print(f"  {'*' * (2*i+1):^9}")

Quick Data Analysis

A DataFrame and its summary statistics.

import pandas as pd
data = {"Name": ["Alice", "Bob", "Charlie"], "Score": [92, 87, 95]}
df = pd.DataFrame(data)
print(df.describe())

Visualize Something

Sine and cosine waves with Matplotlib.

import matplotlib.pyplot as plt
import numpy as np
x = np.linspace(0, 10, 100)
plt.plot(x, np.sin(x), label="sin(x)")
plt.plot(x, np.cos(x), label="cos(x)")
plt.legend()
plt.title("Trigonometric Functions")
plt.show()

Explore Python Itself

The Zen of Python, built into the language.

What it looks like

The editor running a turtle program: a spiral of squares drawn in blue and yellow beside the code — Change a number and run it again: try `t.left(90)` in place of 91.
Run, or press `Ctrl+Enter`.
Turtle drawings, charts and tkinter windows open beside the code.
Share makes a link with your code in it.

Code runs inside your browser's sandbox, so it cannot delete your files or change your system, and it is saved in this browser. No installation and no account: it works on laptops, tablets and Chromebooks.

More Than a Playground

The same editor also has:

Multi-file projects: a tab for each file, and imports between them.
Jupyter-style notebooks: code, output and notes in one document.
Practice problems: 50 problems from beginner to advanced, each with a Check button.
Tutorials: ThePythonBook goes from your first program to data science and object-oriented programming, with runnable examples in every lesson.
