thanks all for the info - and yes - speed is not really an issue and no - it is not an implementation of a complete financial system - but rather a small subset of a investment portfolio management system developed by "another company" ...
What I am trying to achieve is to parse a formula(s) and generate a result ... I will look into the pyparsing suggested and maybe even leave out numarrays for now - as it seems a bit overkill ... The formula are a bit complex and maybe even difficult to write out Thanks all - I will post my progress ;) -- http://mail.python.org/mailman/listinfo/python-list
