A nice parsing library is pyparsing:
http://pyparsing.wikispaces.com/
It contains a parser for mathematical expressions.
There are examples in the source distribution.

How would I go about writing a fast token parser to parse a string like
"[4d6.takeHighest(3)+(2d6*3)-5.5]"
and get a list like
['+',
['takeHighest',
['d',
4,
6
],
3
],
['-',
['*',
['d',
2,
