fib = {1: 1, 2: 1, 3: 2, 4: 3} print(fib.get(4, 0) + fib.get(7, 5))

What is the output? it is shown the output as 8. How does it come?

get(4,0) tries to fetch the value associated with key 4, and if that key is not found, returns 0. In this case, there's a value for key 4, which is 3, thus 3 is returned. Similarly, get(7,5) looks for key 7 into the dictionary. But there's no such key, and then the default value 5 is returned. Now do the math: 3 + 5.

The get not explained very well... Syntax Following is the syntax for get() method − dict.get(key, default=None) Parameters key -- This is the Key to be searched in the dictionary. default -- This is the Value to be returned in case key does not exist. Return Value This method return a value for the given key. If key is not available, then returns default value None.
