There is also dotprint(). That, along with srepr(), is what the tutorial uses to explain how expressions are implemented as a tree(*) http://docs.sympy.org/latest/tutorial/manipulation.html. In the SymPy Live shell, you can change the output format to Repr to always get the srepr() form of an expression.
(*) actually a DAG. Common subexpressions may be the same object. This is done for all singletonized objects in S, and also for many other objects when the cache is enabled.
