Let's analyze the Python code step by step:

python
a = "Sun"
b = "Moon"
c = a
a = b
b = c
print(a + " and " + b)

Step-by-step breakdown:
1. `a = "Sun"` β†’ variable `a` now holds `"Sun"`.
2. `b = "Moon"` β†’ variable `b` now holds `"Moon"`.
3. `c = a` β†’ variable `c` is assigned the value of `a`, which is `"Sun"`.
4. `a = b` β†’ variable `a` is now assigned the value of `b`, which is `"Moon"`.
5. `b = c` β†’ variable `b` is now assigned the value of `c`, which is `"Sun"`.

Final values:
-a = "Moon"
-b = "Sun"`

So, the `print(a + " and " + b)` will output:


Moon and Sun

βœ… Correct answer: A. Moon and Sun

a = "10" β†’ Variable a is assigned the string "10".

b = a β†’ Variable b also holds the string "10" (but it's not used afterward).

a = a * 2 β†’ Since a is a string, multiplying it by an integer results in string repetition.

"10" * 2 results in "1010"

print(a) β†’ prints the new value of a, which is "1010".


βœ… Correct answer: D. 1010
Let’s analyze the Python code snippet from the image:

python
Copy
Edit
def add_n(a, b):
return (a + b)

a = 5
b = 5

print(add_n(4, 3))
Step-by-step explanation:
A function add_n(a, b) is defined to return the sum of a and b.

The variables a = 5 and b = 5 are declared but not used inside the function call β€” they are irrelevant in this context.

The function is called with explicit arguments: add_n(4, 3), so:

python
Copy
Edit
return 4 + 3 # = 7

βœ… Correct answer: C. 7
