Reading the language tututorial would help you a lot :(

=== what is the difference between pc and pc()?

pc = getToolByName(....)  - returnes a refference to a method

pc is a refference to a method, pc() is a method invocation.

============

       	   numbers = {"total":len(results),"bytype":{},"bystate":{}}
<=== This is hard to understand
           num = numbers["bytype"].get(ctype, 0)  <==== where does .get
come from? and what is the string 'bytype' doing?
           numbers["bytype"][ctype] = num    <====== is this some kind
of an array? 

Read the tutorial especially portion about dictionaries!
