As
a dynamic programming language, Python is being used by developers
across the world as a scripting as well as general-purpose language. The
open source language further enables developers to express concepts
without writing lengthy code, while facilitating code reusability.
Python is also used by developers as easy-to-use scripting or automation
interfaces required by applications written in other programming
languages. A programmer can further avail several new modules by opting
for Python 3.
New Models Added to Python 3 to Make It More Powerful
Concurrent.futures: The
module provides a high-level interface that can be used by programmers
to execute the callables in an asynchronous manner. However, the
asynchronous execution of callable can be performed in a number of ways.
The developer can use ThreadPoolExecutor to execute the callable
through threads. Also, he can use the ProcessPoolExecutor to make the
execution a separate process. But each method requires the same
interface that is defined by the abstract Executor class.
Faulthandler: As
the name indicates, the module includes the function required to
explicitly dump Python tracebacks. The functions are executed when the
application faces stops performing due to a fault, user signal or
timeout. The faulthandler.enable() function is called to install fault
handles for SIGFPE, SIGABRT, SIGILL, SIGBUS and SIGSEGV. The functions
can be setup during the project startup either by using the X
faulthandler command line option or by setting the PYTHONFAULTHANDLER
environment variable:
Importlib: The
importlib module can be used for two distinct purposes. Firstly, a
programmer can implement the import statement within the Python source
code. In addition to being portable to the Python interpreter, the
module makes it easier for developers to comprehend the implementation.
Secondly, the programmer can create custom objects that will participate
in the process of importaing the components.
Ipaddress: The
module enables developers to create, operate and manipulate on IPv4 and
IPv6 addresses and networks. They can simply use the functions and
classes included in this module to handle a variety of IP address
related tasks including validating a network definition or IP address,
and checking if multiple hosts are on a single subnet.
Unittest.mock: The
module makes it easier for developers to test the Python application.
The QA professionals can replace certain parts of the application with
mock objects while testing the application, and make assertions about
their usage. The core Mock class provided by the module helps
programmers in not creating additional stubs throughout the testing
suite. Along with being easy to use, the module is also designed with
the features required for unit testing.
Selectors: The
selectors module is designed based on select module primitives. It can
be used by Python developers for high-level and efficient I/O
multiplexing. Further, the programmers can exercise tight control over
the OS-level primitives used. In addition to the BaseSelector abstract
base class, the module also defines a set of concrete implementation for
I/O multiplexing. However, the types of file object supported by the
module with vary from one operating system to another.
Statistics: The
module provides the functions required for calculating mathematical
statistics of numeric data. These functions further support a wide range
of numeric data types including int, float and decimal. However,
currently the module does not support the behavior of several data
types. The developers have to define mixed types specifically, and
implement them according to the requirements of the project.
Recently,
Python 3.4 was released with a set of new features to complement the
latest trends in software development. The most recent version of the
open source programming language comes with a new feature called asyncio
that provides Asynchronous IO support. Further, Python 3.4 comes with a
set of advanced features to meet the requirements of Cloud developers.
