Great news for Python developers. Two release candidates for versions 3.5.4 and 3.4.7 has been released. Let's see what's inside for each version.

Python 3.5.4rc1

Python 3.5.4 will be the last "bugfixes" release of 3.5. After 3.5.4 final is released, 3.5 will enter "security fixes only" mode, and as such the only improvements made in the 3.5 branch will be security fixes.

Features and changes:

  • improved Python zip application support
  • additional unpacking generalizations
  • "%-formatting" for bytes and bytearray objects
  • a new operator (@) for matrix multiplication
  • os.scandir(), a fast new directory traversal function
  • adding support for automatic retries of interrupted system calls
  • change StopIteration handling inside generators
  • the typing module, a new standard for type annotations
  • math.isclose(), a function for testing approximate equality
  • making the Windows Python launcher aware of virtual environments
  • eliminating .pyo files
  •  a new and improved mechanism for loading extension modules
  • coroutines with async and await syntax

Python 3.4.7rc1

Python 3.4 has now entered "security fixes only" mode, and as such the only improvements between Python 3.4.6 and Python 3.4.7 are security fixes. Also, Python 3.4.7 has only been released in source code form; no more official binary installers will be produced.

Features and changes:

Python 3.4 includes a range of improvements of the 3.x series, including hundreds of small improvements and bug fixes. Among the new major new features and changes in the 3.4 release series are:

  • "pathlib" module providing object-oriented filesystem paths
  • a standardized "enum" module
  • a build enhancement that will help generate introspection information for builtins
  • improved semantics for object finalization
  • adding single-dispatch generic functions to the standard library
  • a new C API for implementing custom memory allocators
  • changing file descriptors to not be inherited by default in subprocesses
  • a new "statistics" module
  • standardizing module metadata for Python's module import system
  • a bundled installer for the pip package manager
  • a new "tracemalloc" module for tracing Python memory allocations
  • a new hash algorithm for Python strings and binary data
  • a new and improved protocol for pickled objects
  • a new "asyncio" module, a new framework for asynchronous I/O

TIOBE Index June 2019 to be Rolled Out

Java is still on the top, but experts noted fast growth of Python search queries, and they believe it can reach 1st place in 3-4 years
13 June 2019   256

June 2019 TIOBE Index has been released. Analysts noted a sharp increase in the proportion of searches for Python.

This month Python has reached again an all time high in TIOBE index of 8.5%. If Python can keep this pace, it will probably replace C and Java in 3 to 4 years time, thus becoming the most popular programming language of the world. The main reason for this is that software engineering is booming. It attracts lots of newcomers to the field. Java's way of programming is too verbose for beginners. In order to fully understand and run a simple program such as "hello world" in Java you need to have knowledge of classes, static methods and packages. In C this is a bit easier, but then you will be hit in the face with explicit memory management. In Python this is just a one-liner. 
 

TIOBE Team

Experts attributed the growing popularity of Python to the fact that now many have hit the development of software. And newcomers prefer Python - succinct and concise. According to analysts, Java for beginners is too verbose, and C sooner or later will force to understand the intricacies of memory management.
