%description

Python is an accessible, high-level, dynamically typed, interpreted programming

language, designed with an emphasis on code readability.

It includes an extensive standard library, and has a vast ecosystem of

third-party libraries.

The %{name} package provides the "python3" executable: the reference

interpreter for the Python language, version 3.

The majority of its standard library is provided in the %{name}-libs package,

which should be installed automatically along with %{name}.

The remaining parts of the Python standard library are broken out into the

%{name}-tkinter and %{name}-test packages, which may need to be installed

separately.

Documentation for Python is provided in the %{name}-docs package.

Packages containing additional libraries for Python are generally named with

the "%{name}-" prefix.

Provides: python = %{version}-%{release}

Python extension modules (typically written in C or C++), to embed Python

multi-window text editor with multiple undo, Python colorizing,

smart indent, call tips, auto completion, and other features;

search within any window, replace within editor windows, and

%description debug

python3-debug provides a version of the Python runtime with numerous debugging

features enabled, aimed at advanced Python users such as developers of Python

extension modules.

This version uses more memory and will be slower than the regular Python build,

but is useful for tracking down reference-counting issues and other bugs.

The debug build shares installation directories with the standard Python

runtime. Python modules -- source (.py), bytecode (.pyc), and C-API extensions

(.cpython*.so) -- are compatible between this and the standard version

of Python.

The debug runtime additionally supports debug builds of C-API extensions

(with the "d" ABI flag) for debugging issues in those extensions.
