Spyder

Spyder is a free, open-source IDE for Python aimed at scientific computing and data analysis. It pairs a code editor with IPython consoles for interactive work.

Its Variable Explorer lets you browse and edit objects from the active console, including arrays and pandas objects, via GUI viewers.

Spyder also includes debugging and profiling tools, and it can be extended through plugins. It’s commonly installed via Anaconda, and also offers standalone installers, which are recommended on Windows and macOS.
