- Python 3.0 was released in 2008. Although this version is supposed to be backward incompatibles, later on many of its important features have been backported to be compatible with version 2.7.This tutorial gives enough understanding on Python 3 version programming language. Please refer to this link for our Python 2 tutorial. Why to Learn Python 3?
PythonServer Side ProgrammingProgramming
There is always a debate in the coding community on which python version was the best one to learn: Python 2.x or Python 3.x.
Python is a free and open interpretation programming language whose main strength is its great versatility, as it supports several paradigms, such as its object-oriented programming, with imperative syntax as well as functional, in line with languages such as Haskell.
Below are key differences between pyton 2.x and python 3.x
1. The print function
In python 2.x, “print” is treated as a statement and python 3.x explicitly treats “print” as a function. This means we need to pass the items inside your print to the function parentheses in the standard way otherwise you will get a syntax error.

2. Integer division
Python 2 treats numbers that you type without any digits after the decimal point as integers, which can lead to some unexpected results during division. For example, if you type the expression 3 / 2 in Python 2 code, the result of the evaluation will be 1, not 1.5 as you might expect. It is recommended to use either float(x) instead of using only x in your python 3 code (incase codebase port to python 2) or use from __future__ import division in your python 2 scripts.

3. Unicode Strings
By default, Python 3 stores strings as Unicode whereas Python 2 requires you to mark a string with a “u” if you want to store it as Unicode. Unicode strings are more versatile than ASCII strings, which are the Python 2 default, as they can store letters from foreign languages as well as emoji and the standard Roman letters and numerals.

Output
“string” + b”bytes of data” will through an error.
4. Raising Exception
Python 3 requires different syntax for raising exceptions. If you want to output an error message to the user, you need to use the syntax −
Above syntax works on python 2 and python 3 both.
However, the following code works only in python 2, not in python 3
5. List Comprehension Loop Variables
In python 2, giving the variable that is iterated over in a “for loop” the same name as a global variable may leads to the value of the global variable being changed – which generally we don’t want. This issue has been fixed in Python 3, so you can use a variable name you already used for the control variable in your “for loop” without worrying about it leaking out and messing with the values of the variables in the rest of your code.

Python 3.0 is end-of-lifed with the release of Python 3.1.All users of Python 3.0.x should upgrade to the most recent version ofPython 3; please see the downloads pages.
Python 3.0 has been replaced by a newer bugfix release of Python.Please download Python 3.0.1 instead.
Python 3 Version Windows
Python 3.0 final was released on December 3rd, 2008.
Python 3.0 (a.k.a. 'Python 3000' or 'Py3k') is a newversion of the language that is incompatible with the 2.x line ofreleases. The language is mostly the same, but many details,especially how built-in objects like dictionaries and strings work,have changed considerably, and a lot of deprecated features havefinally been removed. Also, the standard library has been reorganizedin a few prominent places.
