def mystery(a, b = 8, c = -6):
return 2 * b + a + 3 * c

#MAIN
x = int(input("First value: "))
y = int(input("Second value: "))
z = int(input("Third value: "))

1) Suppose we add the following line of code to our program:

print(mystery(x))
What is output when the user enters 1, 1, and 1?

2)Suppose we add the following line of code to our program:

print(mystery(x, y, z))
What is output when the user enters 8, 6, and 4?

Answer:

(a) The output is -1

(b) The output is 32

Explanation:

Given: The above code

Solving (a): The output when 1, 1 and 1 is passed to the function

From the question, we have: print(mystery(x))

This means that only the value of x (which in this case is 1) will be passed to the mystery function

(a, b = 8, c = -6) will then be seen as: (a = 1, b = 8, c = -6)

[tex]2 * b + a + 3 * c = 2 * 8 + 1 + 3 * -6[/tex]

[tex]2 * b + a + 3 * c = -1[/tex]

The output is -1

Solving (b): The output when 8, 6 and 4 is passed to the function

From the question, we have: print(mystery(x,y,z))

This means that values passed to the function are: x = 8, y = 6 and z = 4

(a, b = 8, c = -6) will then be seen as: (a = 8, b = 6, c = 4)

[tex]2 * b + a + 3 * c = 2 * 6 + 8 + 3 * 4[/tex]

[tex]2 * b + a + 3 * c = 32[/tex]

The output is 32

If we add the line of code print(mystery(x)) and our input are 1, 1 and 1 the output will be -1.

If we add the line of code print(mystery(x, y, z)) and our inputs are 8, 6 and 4 the out put will be 32.

This is the python code:

def mystery(a, b = 8, c = -6):

  return 2 * b + a + 3 * c

#MAIN

x = int(input("First value: "))

y = int(input("Second value: "))

z = int(input("Third value: "))

print(mystery(x))

#What is output when the user enters 1, 1, and 1?

#Suppose we add the following line of code to our program:

print(mystery(x, y, z))

#What is output when the user enters 8, 6, and 4?

The code is written in python

The first print statement with the input as 1, 1 and 1 will return -1

The second print statement with the input 8, 6 and 4 will return 32.
