Python 3.4.3 Description
Python 3.4.3 is a remarkably powerful dynamic programming language that is used in a wide variety of application domains. Python 3.4.3 is often compared to Perl, Tcl, Scheme, Ruby or Java.
Fans of Python use the phrase batteries included to describe the standard library, which covers everything from asynchronous processing to zip files. The language itself is a flexible powerhouse that can handle practically any problem domain. Build your own web server in three lines of code. Build flexible data-driven code using Pythons powerful and dynamic introspection capabilities and advanced language features such as meta-classes, duck typing and decorators.
Python 3.4.3 lets you write the code you need, quickly. And, thanks to a highly optimized byte compiler and support libraries, Python code runs more than fast enough for most applications.
- very clear, readable syntax
- strong introspection capabilities
- intuitive object orientation
- natural expression of procedural code
- full modularity, supporting hierarchical packages
- exception-based error handling
- very high level dynamic data types
- extensive standard libraries and third party modules for virtually every task
- extensions and modules easily written in C, C++ (or Java for Jython, or .NET languages for IronPython)
- embeddable within applications as a scripting interface
News in Python 3.4.3:
Core and Builtins:
- Issue #6639: Module-level turtle functions no longer raise TclError after closing the window.
- Issues #814253, #9179: Warnings now are raised when group references and conditional group references are used in lookbehind assertions in regular expressions.
- Issue #23215: Multibyte codecs with custom error handlers that ignores errors consumed too much memory and raised SystemError or MemoryError. Original patch by Aleksi Torhamo.
- Issue #5700: io.FileIO() called flush() after closing the file. flush() was not called in close() if closefd=False.
- Issue #23374: Fixed pydoc failure with non-ASCII files when stdout encoding differs from file system encoding (e.g. on Mac OS).
- Issue #23481: Remove RC4 from the SSL module’s default cipher list.
- Issue #21548: Fix pydoc.synopsis() and pydoc.apropos() on modules with empty docstrings.
- Issue #22885: Fixed arbitrary code execution vulnerability in the dbm.dumb module. Original patch by Claudiu Popa.
- Issue #23146: Fix mishandling of absolute Windows paths with forward slashes in pathlib.
- Issue #23421: Fixed compression in tarfile CLI. Patch by wdv4758h.
- Issue #23361: Fix possible overflow in Windows subprocess creation code.
- Issue #23445: pydebug builds now use “gcc -Og” where possible, to make the resulting executable faster.
