Help me pls about Dictionary function

Question

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))
could you pls explain for me thank you

Answer 1

checks if the dictionary "fib" contains 4, since it does, assigns the value of 4:
fig.get(4, 0) = 3

checks if the dictionary "fib" contains 7, since it doesn't, assigns the secondary value(5):
fig.get(7, 5) = 5

3 + 5 = 8
