%global _description \

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

language, designed with an emphasis on code readibility.\

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

third-party libraries.\

\

The python36 package provides the "python3.6" executable: the reference\

interpreter for the Python language, version 3.\

The package also installs the "python3" executable which is user configurable\

using the "alternatives --config python3" command.\

For the unversioned "python" command, see manual page "unversioned-python".\

\

The python36-devel package contains files for dovelopment of Python application\

and the python36-debug is helpful for debugging.\

\

Packages containing additional libraries for Python 3.6 are generally named\

with the "python3-" prefix.

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.

If you want to build an RPM against the python36 module, you also need to

install the python36-rpm-macros package.

%description debug

python36-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 bytecode format is unchanged, so that .pyc files are compatible between

this and the standard version of Python, but the debugging features mean that

C/C++ extension modules are ABI-incompatible and must be built for each version

separately.

The debug build shares installation directories with the standard Python

runtime, so that .py and .pyc files can be shared.

Compiled extension modules use a special ABI flag ("d") in the filename,

so extensions for both verisons can co-exist in the same directory.
