I'm also interested in this problem. While this solution works, I'm
looking for solution that will also check whether the parameter name/
value is of a certain pattern (these patterns may be different, e.g.
paramA, paramB, paramC may take integers value, while paramD may take
true/false). Is there a way to do this easily?

I'm new to Python and the solution I can think off involve a loop over
a switch (a dictionary with name->function mapping). Is there other,
more elegant solution?
