Integers and Floasts in Python

Defining integers in Python is very easy. eg: answer=42 pi=3.14159 Python 3 also introduces complex numbers as a type.There is no real need to worry about types in Python.atleast not in the beginning. answer + pi = 45.14159 # Don't worry about conversion ! you can seamlessly add integers, float .pyhton does not complain about it.it will produce desired results.And to cast anything.just have to do something like this. int(pi) == 3 float(answer) == 42.0 this is needed when we really want to cast the integer and float variables.
