Single code should run both on python version 3 and version 2.7

Question

How to take list of list (matrix) as input from the user such that the same code should run on both python version 3 and version 2.7
Also the type of the 2D list must be of same type(i.e. int)

Answer 1

You can use an "if" statement to run different code according to Python version:

from sys import version_info
if(version_info >= 3.0.0)
your_list = input()
else
your_list = raw_input()

You can also create different functions for different Python versions and call either one from a similar "if" statement.
