The Most Powerful Online Python Compiler

PlayCode's Python compiler is trusted by over 11 million developers worldwide. Write, run, and test your Python code instantly in your browser with zero setup, no installation, and no waiting. Whether you're learning Python, building data science projects, or automating tasks, our online Python compiler provides everything you need.

Unlike traditional online Python interpreters that run code on remote servers, PlayCode runs Python entirely in your browser using WebAssembly (Pyodide). This means your code stays private, execution is instant, and you can even work offline after the initial load.

What is a Python Compiler?

A Python compiler transforms your Python source code into bytecode that can be executed by the Python interpreter. While Python is traditionally known as an interpreted language, modern Python implementations compile code to bytecode before execution. PlayCode's online Python compiler uses Pyodide, which compiles CPython to WebAssembly, bringing the full power of Python to your browser.

This means you get the complete Python 3.11 experience, including the full standard library, asyncio support, and the ability to install packages from PyPI. No configuration, no virtual environments, no pip commands in the terminal. Just write Python and run it.

For web development projects, try our JavaScript Compiler or JavaScript Playground.

Run Python with Full Package Support

Unlike other online Python compilers that only support the standard library, PlayCode lets you install packages from PyPI using micropip. Install NumPy, Pandas, Requests, BeautifulSoup, and thousands of other packages with a single line of code.

Data Science

NumPy, Pandas, SciPy for data manipulation and scientific computing.

Web & APIs

Requests, httpx, beautifulsoup4 for web scraping and API calls.

Utilities

PyYAML, python-dateutil, regex, and many more pure-Python packages.

import micropip
await micropip.install('numpy')
import numpy as np

# Now use NumPy!
 arr = np.array([1, 2, 3, 4, 5])
print(arr.mean()) # Output: 3.0

AI-Powered Python Development

PlayCode is the only Python compiler with a built-in AI coding assistant. Describe what you want to build in plain English, and watch AI write working Python code for you. Need to parse JSON, scrape a website, analyze data, or solve an algorithm? Just ask.

The AI understands Python deeply. It can help you with list comprehensions, decorators, context managers, and async/await patterns. It explains errors in plain language and suggests fixes. Whether you're a beginner learning Python or an expert looking to save time, AI assistance makes coding faster and more enjoyable.

Visualize Data with Matplotlib and Plotly

Create stunning data visualizations directly in your browser. PlayCode supports Matplotlib for static charts and Plotly for interactive visualizations. Unlike other online compilers that only show static images, our Python compiler renders interactive Plotly charts you can zoom, pan, and explore.

Build line charts, bar charts, scatter plots, heatmaps, 3D visualizations, and more. Perfect for data science projects, machine learning experiments, or just exploring your data visually. See your results instantly without downloading any files or configuring display settings.

import matplotlib.pyplot as plt

 x = [1, 2, 3, 4, 5]
 y = [2, 4, 6, 8, 10]

 plt.plot(x, y, marker='o')
 plt.title('Simple Line Chart')
 plt.xlabel('X Axis')
 plt.ylabel('Y Axis')
 plt.show()
