%description
Python %{pybasever} 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 %{pkgname} package provides the python%{pybasever} executable: the reference
interpreter for the Python language, version 3 and majority of its standard library.
The remaining parts of the Python standard library are broken out into the
%{pkgname}-tkinter and %{pkgname}-test packages, which may need to be installed
separately.

IDLE for Python %{pybasever} is provided in the %{pkgname}-idle package and
development files are provided through %{pkgname}-devel package


%package devel
Summary: Libraries and header files needed for Python development
Requires: %{name} = %{version}-%{release}

%description devel
This package contains the header files and configuration needed to compile
Python extension modules (typically written in C or C++), to embed Python
into other programs, and to make binary distributions for Python libraries.

It also contains 2to3 tool, an automatic source converter from Python 2.X.


%package idle
Summary: A basic graphical development environment for Python
Requires: %{name} = %{version}-%{release}
Requires: %{name}-tkinter = %{version}-%{release}

%description idle
IDLE is Python's Integrated Development and Learning Environment.

IDLE has the following features: Python shell window (interactive
interpreter) with colorizing of code input, output, and error messages;
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
search through multiple files (grep); debugger with persistent
breakpoints, stepping, and viewing of global and local namespaces;
configuration, browsers, and other dialogs.


%package tkinter
Summary: A GUI toolkit for Python
Requires: %{name} = %{version}-%{release}

Requires: tcl >= 8.6.11
Requires: tk >= 8.6.11

%description tkinter
The Tkinter (Tk interface) library is a graphical user interface toolkit for
the Python programming language.


%package test
Summary: The self-test suite for the main python3 package
Requires: %{name} = %{version}-%{release}

%description test
The self-test suite for the Python interpreter.

This is only useful to test Python itself. For testing general Python code,
you should use the unittest module from %{pkgname}, or a library such as
pytest.
