We have something, but not exactly like in Mathematica. Here is sympy's implementation of deriv_degree http://hg.sympy.org/sympy/file/b4a6e225c34a/sympy/solvers/solvers.py#l377 and here are other examples of matching: http://hg.sympy.org/sympy/file/b4a6e225c34a/sympy/core/tests/test_match.py#l1 E.g. the thing that you were looking for is starting here: http://hg.sympy.org/sympy/file/b4a6e225c34a/sympy/core/tests/test_match.py#l153 some other docs are here: http://docs.sympy.org/tutorial.html#pattern-matching Ondrej --~--~---------~--~----~------------~-------~--~----~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to [EMAIL PROTECTED] For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~----------~----~----~----~------~----~------~--~---
