python3.9 3.9.0~rc1-1~20.04 source package in Ubuntu

 IDLE is an Integrated Development Environment for Python (v3.9).
 IDLE is written using Tkinter and therefore quite platform-independent.

 Python is a high-level, interactive, object-oriented language. Its 3.9 version
 includes an extensive class library with lots of goodies for
 network programming, system administration, sounds and graphics.
 .
 This package contains the shared runtime library, normally not needed
 for programs using the statically linked interpreter.

 The package holds two things:
 .
 - Extensions for a Python interpreter configured with --pydebug.
 - Debug information for standard python extensions.
 .
 See the README.debug for more information.

 Header files, a static library and development tools for building
 Python (v3.9) modules, extending the Python interpreter or embedding
 Python (v3.9) in applications.
 .
 Maintainers of Python packages should read README.maintainers.
 .
 This package contains development files. It is normally not
 used on it's own, but as a dependency of python3.9-dev.

 This package contains some essential modules. It is normally not
 used on it's own, but as a dependency of python3.9-minimal.

 .
 This package contains Python 3.9's standard library. It is normally not
 used on its own, but as a dependency of python3.9.

 The complete testsuite for the Python standard library. Note that
 a subset is found in the libpython3.9-stdlib package, which should
 be enough for other packages to use (please do not build-depend
 on this package, but file a bug report to include additional
 testsuite files in the libpython3.9-stdlib package).

 The package holds two things:
 .
 - A Python interpreter configured with --pydebug. Dynamically loaded modules
   are searched as <foo>_d.so first. Third party extensions need a separate
   build to be used by this interpreter.
 - Debug information for standard python interpreter and extensions.
 .
 See the README.debug for more information.

 These is the official set of documentation for the interactive high-level
 object-oriented language Python (v3.9). All documents are provided
 in HTML format. The package consists of ten documents:
 .
   * What's New in Python3.9
   * Tutorial
   * Python Library Reference
   * Macintosh Module Reference
   * Python Language Reference
   * Extending and Embedding Python
   * Python/C API Reference
   * Installing Python Modules
   * Documenting Python
   * Distributing Python Modules

 Examples, Demos and Tools for Python (v3.9). These are files included in
 the upstream Python distribution (v3.9).

 This package contains the interpreter and some essential modules. It can
 be used in the boot process for some basic tasks.
 See /usr/share/doc/python3.9-minimal/README.Debian for a list of the modules
 contained in this package.
