I'd like to point out that math.hypot is a nontrivial function which
is easy to get wrong:

In [6]: x=1e200; y=1e200;

In [7]: math.hypot(x,y)
Out[7]: 1.414213562373095e+200

In [8]: math.sqrt(x**2+y**2)
<type 'exceptions.OverflowError'>         Traceback (most recent call last)

<type 'exceptions.OverflowError'>: (34, 'Numerical result out of range')
