Quoting Ismael Garrido <[EMAIL PROTECTED]>:
(Newbie looking scared) That's kind of hard for me... Parsing it myself is too complex for me. Also, I hoped Python's math would do the job for me, so I wouldn't have to make what's already done in Python.
Writing (and understanding) grammar is probably easier than you think --- once you get over the syntax. And they are fantastically useful things for doing any sort of parsing. But no matter..
If you are interested in learning about parsing, I suggest looking at pyparsing - it is IMO the easiest of the Python parsing frameworks. It has an example that implements a four-function calculator so that would get you off in the right direction.
