Open the full glossary- PythonA programming language, and also the program that runs it. Almost every AI tool's docs, examples and error messages are written in it.
- pipPython's own installer: it fetches packages from the PyPI repository and puts them into whichever Python you are currently using.

- RuntimeTwo meanings: the program that executes your code (the Python interpreter, Node.js, a browser); and the period while your code is actually running, as opposed to the moment it was written.
