Question

Why does the answer of this question is 8??

What is the result of this code?
fib = {1: 1, 2: 1, 3: 2, 4: 3}
print(fib.get(4, 0) + fib.get(7, 5))

Answer 1

The result is 8 because get retrieves the value at the key specified in the first argument if it exists, otherwise it returns the argument specified in the second argument, or None, if the argument is not present.

So in the print statement fib.get(4,0) returns 3 (value at key 4), and fib.get(7,5) returns 5 (no value at key 7). These add up to 8.
