If you are using ipython, you can use the introspection feature, for example 'sum?', which displays a bunch of information about the function or class, including the docstring. Extra details can be found using 'sum??'.
As a side note, sum() is a built-in python function, and we do not override it. There is summation(), which is the sympy function for evaluating sums.
