Underscores in numeric literals let you break up magic constants to make them easier to read: `1_000_000`
The order of elements in `+**kwargs: keyword+` arguments now preserve their order
The new `secrets` module provides handy helpers for secure token generation in various formats
Starting with Fedora 26, the Fedora system Python includes a backport of Python 3.7's upcoming link:++https://docs.python.org/dev/whatsnew/3.7.html#pep-538-legacy-c-locale-coercion++[locale coercion] feature, which means the Python 3 stack will automatically coerce the C locale to C.UTF-8 by setting the `LC_CTYPE` environment variable (if neither it nor `LC_ALL` are already set) before configuring the process locale. Automatically setting `LC_CTYPE` this way means that both the core interpreter and locale-aware C extensions (such as `readline`) will assume the use of UTF-8 as the default text encoding, rather than ASCII.

Python 3.6 will be the default Python 3 stack in Fedora 26. This is an upgrade from 3.5 which was included in Fedora 25. All packages which depend on Python 3 must be rebuilt. User-written Python 3 scripts and applications may require a small amount of porting; however, Python 3.5 is forward compatible with Python 3.6 for the most part. Python 3.6 Fedora 26'da kurulu olarak gelecek. 3.5 sürümünden yükseltme Fedora 25'te mevcut. Python 3'e dayalı olarak gelen paketlerin hepsi tekrar yapılmalı. Kullanıcı tarafından yazılan Python 3 betiklerinde ve uygulamalarında küçük bir değiştirme gerekebilir. Bununla birlikte Python 3.5 çoğunlukla Python 3.6 ile uyumludur.

File system path protocol: Many more standard library APIs, including the builtin `open()`, now support `pathlib.Path` and `pathlib.PurePath` objects
Fedora 26 brings in a new Python Classroom Lab. A variant of Fedora targeted at teachers and students of the Python programming langugae. A ready to use environment with Python, PyPy 3, virtualenv, tox, git, Jupyter Notebook and more. It's ready in three variants: as a GNOME powered desktop or headless for Vagrant and Docker.
A range of performance improvements.
An ongoing challenge within the Python 3 series has been determining a sensible default strategy for handling the “7-bit ASCII” text encoding assumption currently implied by the use of the default C locale.
