Python 3.x vs Python2.x

1 . New Division Functionality

>>> 1 / 2 # integer truncation (Python 2.X) 

0 

>>> 1.0 / 2.0 # returns real quotient (Python 3.x) 

0.5

 

 

2.PRINT 

 

Python2.x                                      Python3.x 

print 'hello world'     print('hello world')

 

 statement                       fumction

3.Range Function

 

In Python3.x we get a new option for range function. We can extract the first term, last term and rest of the list separately. This option was not available in Python2.x. We had to write separate code to extract these values.

 (a, *rest, b) = range(5) 

print (a) 

0 

print(b) 

4 

print(rest) 

[1, 2, 3]

 

This code section will generate a syntax error in Python2.x.

 

4.Not Equal To

 

‘<>’ symbol used in Python2.x to represent not equal to is no longer available in Python3.x. If we try it it will generate a syntax error. The symbol ‘!=’ is used instead, which was available in Python2.x along with ‘<>’.
