Listing out the major features or statements which are having difference between Python 2.x and Python 3.x.
1 ) Print
2) Range functions
4) division operator
5) feature module
6) Exception handling
7) input function
8) object return type for some of inbuilt functions
print ‘Hello Welcome’
Note: In Python 3 print should be use like function
combining both range and xrange in Python 2.x will make range in python 3 with xrange behavior.by default python 3.x range provides iterators object.
In Python 2.x strings are ASCII but in Python 3.x strings are by default Unicode.
In Python if you do division ( 7/5 ) then will get result as 1 but in Python 3 division gives with floating number (like 7/5->1.4).
Python 3.x feature modules add some extra attributes which are not available in Python 2.x and by using those things we can give backward compatibility for some of python 3.x features
from feature import division
There is a small change in exception handling while using exception block , in Python 3.x you need to be handle exceptions by as keyword.
except error as err:
In Python 2.x we have two functions to take inputs from user like input ( depends on user provided value )& raw_input (everything is string) .
to combining these two functions in Python 3.x introduces only input function which takes everything as string.
Object return type for some of inbuilt functions
In Python 2.x some of the inbuilt functions provides list as a output but in Python 3.x all built in functions returns by default iterator object.
zip, map, filter, dictionary keys, dictionary values, dictionary items, range
