Blockly for Parallel Programming in Python -- Getting Started

[ADYoung]

I'm trying to implement some custom blocks to help teach parallel programming and I have a few questions.

First, to import the threading library, it looks like I would include threading in the list of reserved words (as in math.js in generators/python) with

Blockly.Python.addReservedWords('threading');

Then am I to include something like

Blockly.Python.definitions_['import_threading'] = 'import threading';

in every block that uses threading?

Next, as an example, I'd like to create a SummingThread block that takes two inputs.

class SummingThread(threading.Thread):

     def __init__(self,low,high):

         threading.Thread.__init__(self)

         self.low=low
         self

         self.high=high
         self

         self.total=0

     def run(self):

         for i in range(self.low,self.high):

             self.total+=i

thread1 = SummingThread(0,500000)

thread2 = SummingThread(500000,1000000)

thread1.start() # This actually causes the thread to run

thread2.start()

thread1.join()  # This waits until the thread has completed

thread2.join()  

# At this point, both threads have completed

result = thread1.total + thread2.total

print result

I'm not sure how to get started creating a generator to do this -- specifically making a generator to work with classes. Any help is appreciated!

Did you ever get this to work? I am trying to find content for a 100 girls of code event that will use a cluster.
