Predict the output: (a) d = {(1, 2):1, (2, 3):2} print (d[1, 2])

Q. Predict the output:

(a)

d = {(1, 2):1, (2, 3):2}

print (d[1, 2])

(b)

d = {'a': 1, 'b':2, 'c':3}

print (d['a', 'b'])

Answer :-

(a)

1
>>>

Because 1,2 is the key of the dictionary it can be written as d[ ( 1, 2 ) ].

(b)

Error : (
Because there must be only one key in the square bracket. So, the correct code is:-
print( d['a'] , d['b'] )
So, the Output will be:-

1 2
>>>
