Can I use it within Sage? Thanks, RolandRolandbSat, 19 Jan 2013 03:04:51 -0600http://ask.sagemath.org/question/9721/Traversing sage's symbolic expression trees in pythonhttp://ask.sagemath.org/question/9503/traversing-sages-symbolic-expression-trees-in-python/I'm writing some python code around sage and I need to build an expression tree of the following basic form:
- each node represents an operation
- each child tree represents an expression tree to which the operation applies
Can anyone point me in the right direction as to how to traverse an instance of `sage.symbolic.expression.Expression`, so as to extract this kind of semantic information? rmp251Mon, 12 Nov 2012 11:16:40 -0600http://ask.sagemath.org/question/9503/
