Spyder
What it is
Spyder is a free scientific Python environment for scientists, engineers and data analysts. Its multi-language editor offers code completion, real-time analysis, syntax highlighting and split panels, and can run full files, selected lines or code cells in an IPython Console. The console includes function calltips, debugger integration, a Variable Explorer and plots. Standalone installers for Windows, macOS and Linux include common scientific libraries such as NumPy, SciPy, Pandas and Matplotlib. Spyder also connects to existing local or remote Python kernels and supports third-party plugins. The documentation recommends Conda-based installation for plugin use; standalone plugin installation is still under development. For browser access, Binder provides a Spyder session without installation, but code and data are lost when the tab is closed or left. Spyder is open-source and free to use, with documentation pointing users to its FAQ, troubleshooting guide, GitHub issue tracker and Google Group for help.
For and against
For
- Free and open-source.
- Runs files, selected lines and code cells.
- Console includes debugger integration and a Variable Explorer.
- Standalone installers include common scientific libraries.
- Connects to local or remote Python kernels.
Against
- Standalone plugin installation is under development.
- Binder code and data are lost when a session ends.
The verdict
Spyder combines Python editing, interactive execution and scientific tools, with desktop installers and browser access through Binder. Conda is recommended for plugin use, and Binder sessions do not retain code or data after the tab is closed or left.
Who it suits
Spyder suits scientists, engineers and data analysts working with Python. It may also fit users who need an editor, interactive console and scientific libraries in one environment.
