An early developer preview of Python 3.8 has been released and despite the fact that 3.8 is still under development, we can already see some major features coming compared to 3.7.
This release is the first out of four planned alpha releases with the next one coming up on the 24th of February.
Before we have a closer look at Python 3.8.0a1, here is the expected schedule:
Python 3.8.0a1
As an alpha release, Python 3.8.0a1, is intended to make it easier to test the current state of new features and bug fixes and to test the release process. What’s more, during the alpha phase, new features may be added until the beta phase starts.
Most of the new features of Python 3.8 are still under heavy development but there are a couple of major features we know are coming in the next version. Namely:
PEP 572: Assignment expressions – This is a proposal for creating a way to assign to variables within an expression using the notation NAME := expr. A new exception, TargetScopeError is added, and there is one change to evaluation order.
BPO 35766: typed_ast is merged back to CPython – This document describes the development and release schedule for Python 3.8. The schedule primarily concerns itself with PEP-sized items.
You should also keep in mind that this is a preview release and its use is not recommended for production environments.
