What are the new features of Python 3.6 coming soon?

Before the release of the new version, let's look at some important new features.

1. Formatting string literals

    • PEP 498 introduces F-string, a new type of string literal. Chinese translates to "format string literal". This string f is prefixed with a string that is str.format() accepted by a similar method. The replaceable fields are {} wrapped up and evaluated at run time. Specific code examples:
>>> width = 10>>> precision = 4>>> value = decimal.Decimal("12.34567")>>> f"result: {value:{width}.{precision}}"  # nested fields'result:      12.35'

2. Variable comment syntax

    • Previously, Python has added a standard for annotating function variable types, which is type hint. Python 3.6 Adds the ability to annotate more variable types, including class variables and instance variables, based on PEP 526 's proposal.
captain: str # 未设置初始值class Starship:    stats: Didct[str, int] = {}
    • Unlike variable declarations in static languages, variable declarations in Python are designed to make it easier to provide structured type metadata for third-party tools and libraries. Tools that will use the new syntax include: Mypy,pytype,pycharm, and so on.

3. Numeric literals using underscores

    • For larger numbers, too many digits may not be good for judging how big the value is. Now the new version will allow you to use underscores in your digital literals to improve readability.
>>> 1_000_000_000_000_0001000000000000000>>> 0x_FF_FF_FF_FF4294967295

4. Asynchronous generators

    • In the previous release, Python introduced support for the native coprocessor, which can be used async or await syntactically, but there is a limitation that there is no way to use and in the same function body await yield . This restriction is canceled in version 3.6, so you will be able to define an asynchronous generator later. With the new syntax, you can make your code more concise and run faster.
async def ticker(delay, to):    """Yield numbers from 0 to *to* every *delay* seconds."""    for i in range(to):        yield i        await asyncio.sleep(delay)

5. Asynchronous derivation

    • Derivation (comprehension) is itself a great syntactic sugar in python. In the new version, it will get a major upgrade. PEP 530 proposes the use of syntax in lists, tuples, dictionary derivations, or builder expressions async for . In this way, the original various derivations can be converted to support asynchrony. Also, expressions are supported in the derivation await .

Some libraries have been added to the new version, and it has been heard that the dictionary type has been re-implemented, and the elements inside will be ordered.

Linux Release CentOS 7.3 release

CentOS 7.3 is released and CentOS is the product of the re-compiling of the source code for Rhel (Red Hat Enterprise Linux), and there are many known bugs fixed on the basis of Rhel, and its stability is trustworthy relative to other Linux distributions. Major update:

Java Development Tools IntelliJ idea 2016.3.1 release

IntelliJ idea was released in 2016.3.1. If you haven't tried IntelliJ idea 2016.3, you're welcome to use IntelliJ idea 2016.3.1, and This update brings a lot of important bug fixes.

    • One of the most notable changes is the support for JUnit 5 M3, if you plan to continue with JUnit 5 M2, you must use IntelliJ idea 2016.3 (or earlier), or manually introduce attributes from the classpath of JUnit 5 M2.
    • As for JDK 9,intellij idea 2016.3 will not support builds 148 and above because they contain destructive code. Efforts are now being made to resolve this issue, and the version that supports the latest JDK 9 will be released at 2017.1 (its EAP may start in the next few weeks)

Android Studio 2.3 Canary 3 Release

Android Studio 2.3 Canary version 3 has been released to Canary and Dev channels. In addition to a number of common bug fixes, there are some notable changes in this release:

1. Instant run (Instant running)

    • The way Instant Run works in this release has been significantly changed. Changes to the running app are no longer associated with the Play.png run button. The Run button will now always perform an app restart. To make code and resource changes in a running process, there is a new Hot-reload.png button next to it, "Apply changes", which attempts to transfer the changes to the application. (keyboard shortcuts for applying changes are cmd-ctrl-r on Control-f10,mac on Windows and Linux).

    • The purpose of this change is to make the run button more reliable. By running, you can always make sure that the changes are reflected in the running application. Applying changes is now a separate action taken when making adjustments. The Run button continues to use cold swap (cold swap) to build the program faster than reinstalling the full APK, but it is limited to Lollipop.

2. Build cache (Build caching)

    • In Android Studio 2.3 Canary 1, a new build cache was enabled by default (it uses a cross-project shared directory to extract and compile the library). This eventually breaks down several features in the IDE, which make assumptions about the location of the library. In Android Studio 2.3 Canary 3, most of these errors have been fixed; There are also some superficial things remaining (such as listing the library version in the merged manifest editor and the document Pop-up window), and subsequent fixes will continue.

3. Layout Editor

    • There are several new features in the layout editor. First, the palette has been completely rewritten. The new palette provides a preview of widgets, better sorting, and search and filtering: Click the search icon findplain.png to find widgets. Second, search and filter can now also work in the property inspector. Third, the set of properties that can be displayed in the inspector for the specified widget custom type. In all property sheets, click the Star icon favorites.png to bookmark the properties of this type of widget that you want to view, and from now on, these properties will appear in the Favorites section of the component Inspector.

4. App links Assistant (App link assistant)

    • The Android app link allows users to seamlessly connect to your app experience. Now it's easier to add support for Android app links in your app. Just go to [tools] > [app link Assistant] in Android Studio to get started.

5. Lint

    • The command line HTML reports has been overhauled-no longer the old dark holo appearance, now has a Material design look, and includes code snippet syntax highlighting and more.

6.Data binding (data binding)

    • Fixed several editor errors, including common feature expression issues. The editor parser can now handle these correctly.

7. Dual Debugger (Dual debugger)

    • The Hybrid debugger has been renamed to a dual debugger.

8. Proguard version Update (Proguard edition upgrade)

    • The Android plugin for Gradle uses the Proguard version to upgrade to 5.3.2.

9. SDK Patches (SDK patch)

    • Patches are now being provided for the SDK after the SDK update has been patched. Over the next few weeks, more patches will continue to be provided for more components.

Android Studio 2.3 Beta1 released, 2.3 first beta

This version and the December 13 release of Android Studio 2.3 Canary 3 are not very different, mainly the IDE has been modified :

    • In Android Studio 2.3 Canary 1, the underlying IDE has been upgraded from IntelliJ 2016.1 to 2016.2, adding many new features-ligatures, breadcrumbs, editor background images, redesigned UI, and more. BETA1 contains some additional patches in OpenJDK to help MAC users running Sierra.
