I've always thought of it like this... in C, we have to do something 
like this when declaring a variable:

int x = 0;

We had to specifically tell the language compiler that x is an integer. 
In Python, all we have to do is:

x = 0

The interpretor knows that x is an integer. We can also change the type 
like this:

str(x)
float(x)
long(x)

etc...

To me, this is why Python types are called dynamic. They are easy to 
setup and easy to modify when compared to older, more static languages.
