Simple Programming Question

Hi All,

Forgive my ignorance, but I am writing a program where I have a set of commands that occur for a given number of trials (for in in range (0, No_trials)).

I wish to have another event that only occurs every three trials (i.e. when i is 3, 6, 9 etc) - can anyone tell me how I would express this in Python?

Many thanks

Mark

Are you using the viztask module to run your trials? Either way, here is some code that shows how you can detect every third trial:

Code:

import viz

import viztask

viz.go()



NUM_TRIALS = 10



def runTrial():



        yield viztask.waitTime(1.0)







def runExperiment():



        for i in range(NUM_TRIALS):



                if i % 3 == 2:

                        print 'Special event for every third trial'



                yield runTrial()



                print 'Finished trial',i+1



viztask.schedule( runExperiment() )
