About Pyzo
Pyzo is a Python IDE that combines an editor, an interactive shell and a set of tools to help the programmer. It works with any Python interpreter installed on the system, including Conda environments, rather than bundling its own.
The focus on interactivity and simplicity makes it a free alternative for people used to MATLAB, as well as for students and scientists who want to run code step by step. It remains actively developed, with version 4.22.0 released in July 2026.
