#part a)
trials=[]
for word in ['red','green','blue']:
    for ink in ['red','green','blue']:
        thisTrial = {'word':word, 'ink':ink}
        trials.append( thisTrial )

#part b)
for thisTrial in trials:
    print(thisTrial['word'], thisTrial['ink'])

#part c)
print(trials[3]['ink']) #4th entry has index 3 BECAUSE WE START AT zero

#part d)
for ii, thisTrial in enumerate(trials):
    print(ii, thisTrial['word'], thisTrial['ink'])
