Python tutorial part 8 : setting python path

SETTING PATH IN PYTHON

 

Before starting working with Python, a specific path is to set.

 

Your Python program and executable code can reside in any directory of your system, therefore Operating System provides a specific search path that index the directories Operating System should search for executable code.

The Path is set in the Environment Variable of My Computer properties:

To set path follow the steps:

 

Right click on My Computer ->Properties ->Advanced System setting ->Environment Variable ->New

 

In Variable name write path and in Variable value copy path up to C://Python(i.e., path where Python is installed). Click Ok ->Ok.

 

Path will be set for executing Python programs.

1. Right click on My Computer and click on properties.

2. Click on Advanced System settings

3. Click on Environment Variable tab.

4. Click on new tab of user variables.

5. Write path in variable name.

6. Copy the path of Python folder.

7. Paste path of Python in variable value.

8. Click on Ok button:

9. Click on Ok button:

Python tutorial part 4 : python history

Python History

 

Python laid its foundation in the late 1980s.

The implementation of Python was started in the December 1989 by Guido Van Rossum at CWI in Netherland.

In February 1991, van Rossum published the code (labeled version 0.9.0) to alt.sources.

In 1994, Python 1.0 was released with new features like: lambda, map, filter, and reduce.

Python 2.0 added new features like: list comprehensions, garbage collection system.

On December 3, 2008, Python 3.0 (also called "Py3K") was released. It was designed to rectify fundamental flaw of the language.

ABC programming language is said to be the predecessor of Python language which was capable of Exception Handling and interfacing with Amoeba Operating System.

Python is influenced by following programming languages:

ABC language.

Modula-3

 

Python tutorial part 3 : python features

Python Features

 

Python provides lots of features that are listed below.

 

1) Easy to Learn and Use

Python is easy to learn and use. It is developer-friendly and high level programming language.

 

2) Expressive Language

Python language is more expressive means that it is more understandable and readable.

 

3) Interpreted Language

Python is an interpreted language i.e. interpreter executes the code line by line at a time. This makes debugging easy and thus suitable for beginners.

 

4) Cross-platform Language

Python can run equally on different platforms such as Windows, Linux, Unix and Macintosh etc. So, we can say that Python is a portable language.

 

5) Free and Open Source

Python language is freely available at offical web address (https://www.python.org/).The source-code is also available. Therefore it is open source.

 

6) Object-Oriented Language

Python supports object oriented language and concepts of classes and objects come into existence.

 

7) Extensible

It implies that other languages such as C/C++ can be used to compile the code and thus it can be used further in our python code.

 

8) Large Standard Library

Python has a large and broad library and provide rich set of module and functions for rapid application development.

 

9) GUI Programming Support

Graphical user interfaces can be developed using Python.

 

10) Integrated

It can be easily integrated with languages like C, C++, JAVA etc.

 

Python tutorial part 2 : python introduction

Python is a general purpose, dynamic, high level and interpreted programming language. It supports Object Oriented programming approach to develop applications. It is simple and easy to learn and provides lots of high-level data structures.

 

Python is easy to learn yet powerful and versatile scripting language which makes it attractive for Application Development.

 

Python's syntax and dynamic typing with its interpreted nature, makes it an ideal language for scripting and rapid application development.

 

Python supports multiple programming pattern, including object oriented, imperative and functional or procedural programming styles.

 

Python is not intended to work on special area such as web programming. That is why it is known as multipurpose because it can be used with web, enterprise, 3D CAD etc.

 

We don't need to use data types to declare variable because it is dynamically typed so we can write a=10 to assign an integer value in an integer variable.

 

Python makes the development and debugging fast because there is no compilation step included in python development and edit-test-debug cycle is very fast.
