What is a Python interpreter?

A Python interpreter is the program that reads Python source and runs it. Locally that is usually CPython. This page runs CPython via Pyodide (WebAssembly) in your browser so you can execute code without installing Python.

Can I run Python online for free?

Yes. This Python interpreter is free, needs no account, and runs your code in the browser. You can write, run, copy, and download scripts at no charge.

Do I need to install Python?

No. The runtime downloads into your browser on first run. You do not need to install Python on Windows, macOS, or a tablet to use this tool.

Which Python version does the interpreter use?

The status bar shows the exact Python version reported by the runtime after it loads (CPython inside Pyodide). Do not assume a version until that status says ready.

Can I use Python packages?

Standard library modules such as math, json, random, and statistics work. This is not a full desktop install: arbitrary PyPI packages are not installed. If a module is missing you will see a short explanation in the Output panel.

Is my Python code uploaded to the server?

No. Execution is client-side. Binary Tech does not need to upload your Python code to a server to run it. Avoid putting secrets in any online editor anyway.

Yes. When your program calls input(), the Output panel shows a console prompt. Type a line and press Enter to continue. Do not rely on a browser popup.

Can I download my Python code?

Yes. Use Download to save the editor contents as python-code.py, or Copy to place the code on your clipboard.
