In Python v2, input() reads a string and tries to interpret it. For instance an answer of 2+3 to input() will make input() return the int object 3. By contrast, raw_input() returns the entered string, no more, no less, so it would return the str object 2+3.

This behavior of input() is now considered dangerous and not very usable anyway so In Python v3, input() behaves likes v2 raw_input().
