Which of the following is not a valid way to define this dictionary in Python:
d = dict([
('foo', 100),
('bar', 200),
('baz', 300)
])
d = {}
d['foo'] = 100
d['bar'] = 200
d['baz'] = 300
d = dict(foo=100, bar=200, baz=300)
d = {'foo': 100, 'bar': 200, 'baz': 300}
d = { ('foo', 100), ('bar', 200), ('baz', 300) }
Consider this dictionary:
d = {'foo': 100, 'bar': 200, 'baz': 300}
What is the result of this statement:
d['bar':'baz']
It raises an exception
(200, 300)
200 300
[200, 300]
Suppose x is defined as follows:

'y' : 20,
'z' : 30
},
'baz': 3
},
'c',
'd'
]
What is the expression involving x that accesses the value 30?
x[2]["bar"]["z"]
x[2]["bar"]
