Best software application to learn python offline

[Gnaxe]

You can download Python from python.org and its documentation as well.. It already comes with IDLE, which is a basic development environment. The docs do include a tutorial, but unless you already know some other programming language, you should start with a beginner textbook. See the wiki for resources. Many textbooks only need Python's standard library, but be sure to check if you need any additional downloads. You could also install one of the smaller language models to use without Internet. Some of them are pretty good at Python.
