This is a web log file analyzer we are making using python. First the IIS parsing engine wil be built and then Apache and possibly other servers. It is going to support multiple log files from any date and output the statistics in html formatted files, incorporating automatically build charts. It will be a pure python solution which is going to be self contained, ie no installation will be required other from the standard python modules.
Main point is parsing documents with regular expression to the tree and edit them or replace some of the data, powered by your own pythoncode. Python is very easy to understand, don`t be worried about this and try it! ;-)
