Hi I've some trivial question: for exercise I want to parse a string that like this:
"x -34 + 65 * 96 = 102" now if I had this ("(25+24)/2") is extremely easy to have a result but I want to resolve the above string (for the 'x' variable) what can I do? Especially for symbolic function I think that I've to build an 'operations tree' with a variable table. I want to know how Derive parse this kind of string. If I've to build a tree, please give me resources and/or examples of what physically is a tree and how to build on python. Thanks :) -- http://mail.python.org/mailman/listinfo/python-list
