NINJA-IDE vs Pyzo

NINJA-IDE is a free integrated development environment for creating applications, with tools for managing Python projects. The editor provides syntax highlighting, code completion, and help with imports and navigation. A code locator gives access to project files, functions, and classes, and documents can highlight static and PEP 8 errors. Users can manage files within the IDE, run a Python project or open file with one click, and render HTML files inside the application. Plugins can extend the editor and integrate functionality. The download page lists v2.4 installers for Windows 10/11 and Linux distributions; its macOS entry says the app is unavailable there and offers source code only. Listed requirements are Python 2.7 and PyQt 4.7 or later. The project describes the software as GPLv3+ and lists a mailing list and GitHub issues for questions and bug reports. The website says it is no longer run by the official authors.

Pyzo is a free, open-source Python IDE built for interactive and simple programming. It targets data-centric work including learning, science, data analysis, and application development. The editor provides auto-indentation, syntax highlighting, regular-expression search and replacement, and debugging breakpoints. Its shell can run code, selections, cells, or files, and multiple shells can operate simultaneously with different Python versions. Shells run in interruptible subprocesses. Session and source completion, function call tips, interactive help, a file browser, source structure view, workspace, and logger support development. Pyzo works with system-installed Python interpreters, including Conda environments, and supports pip or conda package management plus several GUI toolkits. It runs on Linux, macOS, and Windows. Running code requires installing both Pyzo and a Python environment.
