In [1]: from scipy import derivative

In [2]: derivative?
Type:           function
Base Class:     <type 'function'>
String Form:    <function derivative at 0x01EC5A30>
Namespace:      Interactive
File:           c:\python24\lib\site-packages\scipy\misc\common.py
Definition:     derivative(func, x0, dx=1.0, n=1, args=(), order=3)
Docstring:
     Given a function, use a central difference formula with spacing dx to
compute the nth derivative at x0.

order is the number of points to use and must be odd.

Warning: Decreasing the step size too small can result in
round-off error.
