Comparing Python 2.x and Python 3.x

Although development of Python started in the late 80’s, Python 1.0 was published in January 1994.

It was designed to rectify certain flaws in earlier version. The guiding principle of Python 3 was: "reduce feature duplication by removing old ways of doing things". Python 3.0 doesn’t provide backward compatibility. That means a Python program written using version 2.x syntax doesn’t execute under python 3.x interpreter. Since all the Python libraries are not fully ported to Python 3, Python Software Foundation continues to support Python 2. The foundation has recently announced it will discontinue Python 2 support by year 2020. Some of the obvious differences between the Python 2.x variants and Python 3.x variants are displayed below. 1. Print Python 2.x It is not mandatory to use pa...

Syntax of Python

What is Syntax ? Computers are machines that can interpret your instructions only if you type them in the exact format that the computer expects. This expected format - the spelling, formatting and grammar - is called the 'Syntax'. For example : #This function divides two numbers def divide(x,y):                                                            return x/y                                                                                                                                    ...

After installing Python, we need to start using it to <CODE>. In this post, we will learn how to use the Python Interpreter IDLE, and how to print "Hello World" using IDLE. So, lets get started. The Python Interpreter we are using here is IDLE (Integrated Development Environment) . Click on START > IDLE It will launch the IDLE Interpreter which looks like this : You can write appropriate python codes after the >>> For example :  The above image shows illustration of +, -, *, /, % These are the basic arithmetic operators, addition (+), subtraction (-), multiplication (*), division (/), modulo (%) and power (**) You can practice with the Code Challenge in the next post.
