Python Tutorial

Python is a high level and highly purpose programming language. Python programming language is referred to as a dynamic programming language. The programs written in python are much easier to understand and take less time to write because it is a high level programming language.

A high level language is portable that is the programs written in the high level language can be run on different computers. Therefore, this is an advantage of python programming language that the programs can be run on different computers. The python programming language is the most powerful and simple language.

Python has an efficient high level data structures and also has an approach to object oriented programming. Python is used for application development and for scripting as well because of its simple syntax and dynamic typing. Python also supports functional programming and procedural styles. The interpreters of python are available on most of the operating systems. There is a comprehensive standard in the python and also supports automatic memory management systems.

Python is mostly used for the development of software at organizations like for Google etc. The programmers can easily solve complex problems using python. Only one interpreter is required to run a program of python that is why python is also considered to be an interpreted programming language.

 

About Python

Python was introduced in the late 1980s by Guido van Rossum at Centrum Wiskundi and Informatica (CWI) in the Netherlands. In October 2000 python 2 was released having many new features. Then in December 2008 python 3 was released that was more compatible. If you want to know more about python you can visit the link http://www.python.org.

From this website you will find various links to download the latest versions of python for Microsoft Windows, Mac OS X, and linux.

 

History of Python

The python was named after a BBC show “Monty Python’s Flying Circus”. Python was named by his creator Guido Van Russom. Guido Van Russom really hated the snakes that kill animals for their own food. The snakes killed the animals by twisting the animals around their long bodies and then crushed them.

The implementation of python was started in December 1989. The language has an ability of handling exceptions and also interfacing with the operating systems. Python is derived from various other programming languages that include C, C++, ABC, etc.

 

Python Programming Features

Object oriented programming and structured programming is fully supported by python and hence it is a multi paradigm programming language. Python is used for application development and for scripting as well because of its simple syntax and dynamic typing. Python also supports functional programming and procedural styles. Python also supports late binding that allows binding variable names and methods during the execution of program. Python is a highly extensible programming language. We can also embed python on different existing applications that require a programmable interface. Python consists of a large standard library. Following are some of the features of python programming language:

Simplicity

Python is very simple and easy to understand programming language. The syntax of python programming language is in simple English that is English like keywords are used and also it uses a less number of punctuation yet very strict English is used as well. The pseudo code of python programming language has great strength. The pseudo code allows the user to understand and to concentrate on the solution of the problem rather than language. It is a highly readable programming language.

Easy to learn

Python has a simple and easy to understand syntax. The syntax is very easy as compared to the other programming languages like C++ etc. Therefore, the whole language is easy to understand.

Free and open source

The software of python programming language can be distributed freely. The user can read the source code and can also make amendments in the code and later can use it in other programs.

High level language

Python is a high level language. Python has an efficient high level data structures and also has an approach to object oriented programming. Python is used for application development and for scripting as well because of its simple syntax and dynamic typing. There are no problems of memory management when using python. The computer directly understands Python as it is in high level language.

Portable

As python has an open source nature therefore, the programs written in python can be used in other platforms as well. The user does not need to do any changes to python programs when using the programs in other system. As an example consider that the programs written in python programming language can be used on Windows, AROS, PlayStation, Macintosh, etc.

Interpreted

As python is a high level language therefore, it is not required to convert it into binary language. Computer directly understands it. The compilation is what when you convert a high level language to a low level language. It means that compilation is not required. The user only writes the program or source code and the program will automatically run. The compilation is done by python itself that is first the source code is converted into a byte codes and then translates it to the language of computer.

As there is no need of compilation therefore, python becomes more portable and the program can be copied directly to other systems.

Object Oriented

Python has an efficient high level data structures and also has an approach to object oriented programming. This means that the programs in python can be divided into sets. This is done by creating objects. Object oriented programming is the name of creating objects in a program. Object oriented programming can be done easily by python as compared to Java or C++.

Extensible

The programs written in python or the python programming can be extended by adding the codes of C or C++ when a high performance for an application is required.

Embeddable

Python can be embedded with other programming languages like C and C++. This adds scripting capabilities to the program source code.

Extensive libraries

The standard library of python is very large. The users can perform many functions such as web browsing, databases, documentation generation, GUI, etc. because of the huge library of python the user does not have to write the whole code by himself.

 

Python Applications:

Python is mostly used as an embedded scripting language. Python programming language is a versatile language. It is mostly used in web development at the back end side. But python becomes slower due to high performance and heavy and complex tasks. Python is also used for software development and in business. Following are some of the applications of python programming language:

Web Development

Python is widely used for web development. Through python the user can build applications using the frameworks. Websites such as Mozilla, Instagram are written in python programming language.

Scientific and Numeric computing

Python supports a hierarchical package thus adding modularity and is widely used from scientific and numeric computing purposes. Python is used for scientific and numeric computing because it can handle exceptions and errors and also manages memory automatically. The python programming can also be used for machine learning.

Creating software Prototypes

Python becomes slower due to high performance and heavy and complex tasks as compared to C and C++ programming languages. The user should not use python when the resources are limited. To create prototypes python is the best option. For example to create a game you can include a header file Pygame. Python provides high level dynamic data types.

GUI programming

Python also supports GUI that is graphical user interface. This is portable and can be ported to other systems such as Macintosh, Windows, UNIX, etc.

Databases

The python programming language also provides databases.
