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

Question

Why this doesn't work

Answer 1

in this (4,0), 4's value is 3 as given in fib
now look at (7,5)..here 7 is not in fib so by default it (get) will take 5.. so now the addition of 3+5=8,so our output is 8.

Answer 2

if the number before the comma is not in the dictionary then number after the comma is taken default 7,5 in this 7 is not in the dictionary so 5 is taken

Answer 3

You do not enter an indent in the beginning of second line, try this:

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

#output = 8

Answer 4

5 got it because it is indicated, if the dictionary does not have the first value, what is indicated is displayed on the screen, separated by commas )

And it turns out that we do not have the first value (7), which means that what is indicated is displayed separated by commas (5)
hence comes:
5 + 3 = 8

Answer 5

So, what I've understood from this in simple English

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

the answer is 8.

Let me explain
fib.get(4,0) is 3 because 4 is on the 3rd dictionary of fib (remember you start counting from 0) which means 1:1 is 0, 2:1 is 1, and so on.

(7,5) is not in the dictionary, so, the second value is taken by default, which also means automatically 5 is taken.

Now adding their results, we have 3 + 5 =8

Answer 6

remove the space at the beginning of the second line
as in,

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

result is 8

Answer 7

Can anyone how it works and let me know the logic

Answer 8

except indebted

Answer 9

I don't understand why or how the value 5 is in place.

Answer 10

8

Answer 11

I don't fully comprehend the logic behind the addition of 5

Answer 12

get cancer whoever made this app

Answer 13

its 8

Answer 14

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

fib.get(4,0) its return value 3 (# 4th value)
fib.get(7,5) its retturn value 5(# specified value)

the key is not found in the dictionary it returns another specified value

print(fib.get(4, 0) + fib.get(7, 5))
print(3+5)
print(8)

Answer 15

8

Answer 16

8

Answer 17

fib = {1: 1, 2: 1, 3: 2, 4: 3}
print(fib.get(4, 0) + fib.get(7, 5))
print(fib.get(4, 0)) this line output is three because it takes the value of key 4. Where as print(fib.get(7, 5)) this one out put is 5 because there is no any any number with the key 7. So it takes its value 5 by defualt

Answer 18

8

Answer 19

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

Answer 20

Still don't get how 5 is in
