Ans.
|
Python2
|
Python3
|
|
It is more stable and transparent version of python programming language.
|
It is future of Python designed to address the design flawn in the previous versions.
|
|
The print syntax is treated as a statement rather than a function that requires text to be wrapped in parenthesis.
|
The print is explicitly treated as a function and replaced by the print() function in Python 3 which requires an extra pair of parenthesis.
|
|
ASCII string type is used by default to store strings.
|
Unicode is the implicit string type by default.
|
|
It simply returns an integer to the nearest whole number when dividing two integers.
|
It makes integer division more intuitive by using true division for integers and floats.
|
|
xrange function reconstructs the sequence every time.
|
