 Python puts a strong emphasis on code readability and (_similar to Haskell_) uses [significant indentation][significant indentation] to denote function, method, and class definitions.
-Code can be written and executed from the command line, in an interactive interpreter session, in [JupyterLab][jupyter] (Jupyter notebook), or a wide variety of [code editors and IDEs][editors for python].

-Tests and tooling for this track currently support `3.10` - `3.13.5` (_tests_) and [`Python 3.13.5`][313-new-features] (_tooling_).
+Tests and tooling for this track currently support `Python 3.10 - 3.13.7` (_tests_) and [`Python 3.13.7`][313-new-features] (_tooling_).
 It is highly recommended that students upgrade to at least `Python 3.10`, as some features used by this track may not be supported in earlier versions.
 That being said, most of the exercises will work with `Python 3.6+`, or even earlier versions.
 But we don't guarantee support for versions not listed under [Active Python Releases][active-python-releases].
 We will try to note when a feature is only available in a certain version.
