Summary

Python is an interpreted, interactive, object-oriented programming language, which includes modules, classes, exceptions, very high level dynamic data types and dynamic typing. Python supports interfaces to many system calls and libraries, as well as to various windowing systems. This package provides the "python3" executable: the reference interpreter for the Python language, version 3. The majority of its standard library is provided in the python3-libs package, which should be installed automatically along with python3. The remaining parts of the Python standard library are broken out into the python3-tkinter and python3-test packages.
Security Fix(es):
* python: Cookie domain check returns incorrect results (CVE-2018-20852)
* python: email.utils.parseaddr wrongly parses email addresses (CVE-2019-16056)
