Question

pairs = {1:2,3:5,6:3}
print(pairs.get(2,0)+pairs.get(6,4))

O/P: 3
Explain the output of this program.

Answer 1

get() takes two arguments, the first is the key to look for, the second one is the value to return if the key is not found. If the key is found then its value is returned, so in this case:
0 + 3 = 3

Answer 2

The get() method returns a value for a given key. If a key doesn't exist, the given value in the 2nd argument is used. It doesn't replace a value if the key exists

key 2 doesn't exist, so the value 0 is used..
key 6 exists, so it's stored value is used, not the given one.
