l = ['Michael', 'Bob', 'Tracy']
l.append('Bob')

scores = [95, 70, 60]

d = {'Michael': 95, 'Bob': 70, 'Tracy': 60}
d['Bob'] = 82
d['Rose'] = 88
d.pop('Bob')

print(d)

sl = {'Michael', 'Bob', 'Tracy'}
s2 = {'Michael', 2, 3}
sl.add(12)
s2.remove(3)
print(sl, s2)

dl = dict(zip(l, scores))
print(1)
print(scores)
